- Based on over 1,000 hours of testing and our survey of 600 adjustable bed owners, we learned that under-bed lighting, a backlit remote, and settings controlled using a mobile app are top priorities for shoppers looking for a new adjustable bed.
- Split king adjustable beds can cost around $1,000 to over $4,700, depending on features, construction, and materials.
If you and your partner struggle to sleep well next to each other, you’re not alone. A recent survey showed one-third of American couples occasionally sleep in separate rooms due to loud snoring or different sleep habits, which can help both partners sleep better. But sleeping together also has mental and emotional benefits, like a decreased risk of depression, anxiety, and overall stress. Is there a way to sleep together but still prioritize our own sleep?
Choosing a new mattress from the best split king adjustable beds may be a good compromise. Split king styles divide the sleeping surface into two independently adjustable surfaces. This allows you to change your position while sleeping together, like elevating the head of the bed to alleviate snoring without disturbing each other’s sleep.
Sifting through options can feel overwhelming, but the Handbook Team is here to help. We evaluated multiple split king adjustable beds on the market so you can select the best adjustable bed that supports your sleep needs, health, and relationship.
7 best split king adjustable beds of 2024
- Saatva: Best overall.
- Nectar: Most comprehensive warranty.
- DreamCloud: Best Bluetooth-enabled
- Brooklyn Bedding: Best value
- Sleep Number: Best mattress-base combo for couple customization.
- Tempur-Pedic: Best advanced technology.

What to look for in split king adjustable bases
- Features: Before buying a split king adjustable bed, consider the features you want in your base. Common features include preset positions, customizable settings, mobile app control, and under-bed lighting.
- Mattress compatibility: Split king adjustable beds are compatible with different mattresses. Keeping in mind your unique comfort needs, consider selecting a few different mattresses that meet those needs first and then find compatible adjustable bases to help narrow down your options.
- User-friendly controls: Split king adjustable beds are controlled by the sleeper, with some using a wireless remote and others relying on a mobile app. Your preferences and comfortability with tech will determine what you find to be user-friendly.
Saatva: Best split king adjustable bed overall
Why Saatva is our pick for best overall
Saatva is the highest-rated brand on the market, offering split king adjustable beds with luxury features at a fair, mid-range price. Keeping in mind our research on what sleepers are looking for in a split king adjustable bed, our testers pointed out that the remote was easy-to-use with backlit buttons. Additionally, this mattress has under-bed lighting and moves smoothly between presets. We also like the appearance of this bed, which is concealed inside the compatible bed frame Saatva sells at an additional price. Like all Saatva products, white glove delivery is included with the purchase of either the Adjustable Base and Adjustable Base Plus.
Who may like Saatva: Because the Saatva Adjustable Base includes free delivery and set up with every purchase, we think it’s a great option for sleepers with mobility issues who need assistance with the setup of their new bed.
Who should consider other options: Because the Saatva Adjustable Base is controlled by remote only, this bed isn’t a great choice for someone who prefers to use a mobile app to control the settings of their bed.
Saatva tester insights
Saatva is the Handbook Team’s top adjustable bed brand because it offers the right mix of style options, features, and services that address most people’s needs at a fair price. It also has the highest customer satisfaction of all competing brands, with more than 1,000 positive reviews on Better Business Bureau and Trustpilot.
Handbook Team Tip #1
When the Handbook Team surveyed 600 adjustable bed users, we found that fair price, multiple features, brand reputation, and in-home delivery were the most important considerations when searching for the right bed. Saatva covers them all.
Of the two Saatva models, we highly recommend the Adjustable Base Plus for couples because of its available styles and features. While both models offer split king options, the Plus comes in split California king and standard split king or queen Upper-Flex options for the same price or similar ($2,598 and $2,498, respectively).
Upper-Flex is the brand’s split-top style that independently adjusts the head for each sleeper while the foot adjusts as one unit. We only recommend split-top styles if you need to elevate your head to alleviate snoring or acid reflux and want to keep the rest of the base whole for more comfortable cuddling without an annoying mattress gap.
All split and Upper-Flex models come with a remote for each side to independently adjust your position and massage settings, so you don’t need to battle over the remote to adjust your side.
The Adjustable Base Plus comes with multiple pre-programmed positions:
- Head up: Fully elevates the head to a seated position.
- Flat: Returns the base to a fully flat position.
- Anti-snore: Elevates the head to 7 degrees to open the airway and reduce snoring.
- Zero gravity: Elevates the head and legs for a cradled position.
You also get many other features, including:
- Memory presets: Program one custom position on your remote’s memory button.
- Head, foot, or full-body massage: Choose up to three intensities to promote relaxation.
- Under-bed lighting and remote flashlight: Light up a dark room to avoid tripping.
- Wall-aligning design: Elevate the head of the bed without distancing yourself from the nightstand.
Saatva ticks most of our boxes except for one: a trial period. The industry standard excludes trial periods and returns because adjustable bases are difficult to move and ship. However, some brands, like Serta and Nectar, still offer a trial period to help you decide if the base works for you.
But we like that Saatva offers a compromise. If you and your partner dislike the split mattresses and the separation between you, Saatva told us they would exchange the two mattresses for one king and guide you through syncing the entire base to work as one unit. This transforms your split king adjustable bed into one king-size adjustable bed, so you and your partner sleep on one large adjustable surface.
Another perk, Saatva also offers white glove delivery (delivering and setting your base) for free, so you don’t have to worry about setting up the base by yourself. Our team found most other brands charge for this service or don’t offer it at all, so this is a major standout service included with your purchase.
From one of our Saatva testers:
“The Adjustable Base Plus has most of the features you would expect from an adjustable base, like under-bed lighting and massage, but it doesn’t have a lot of the fussy features like complicated massage programs or speakers. For an investment like an adjustable base that’s often a final sale, the warranty length, my positive customer service experience, and positive online reviews give me confidence in Saatva.”

Nectar: Most comprehensive split king adjustable bed
Why Nectar is our pick for the most comprehensive
We chose the Nectar Adjustable Frame as the most comprehensive adjustable split king because it includes several features, including settings you can control through a wireless remote and a mobile app. Our testers noted the remote was basic, making it easy to use. This adjustable base has under-bed lighting and allows you to create two custom settings in addition to the included presets. Nectar’s split king allows you to control each side separately or together, depending on sleeper preference. Nectar’s policies are as comprehensive as its bases, offering a 50-night trial period, opportunities to extend your full-coverage warranty by 10 years, and a chance to reduce total cost.
Who may like Nectar: Since the Nectar adjustable bed can be controlled through a mobile app, it’s a good option for someone who prefers to use a smartphone over a remote control.
Who should consider other options: Our tester noted that the base’s massage function is subtle, more of a vibration than a massage, so we don’t recommend it for sleepers who plan to use this feature regularly.
Nectar tester insights
We found the Nectar Adjustable Frame is a valuable purchase for couples who want a split king because it offers what many brands don’t: a chance to extend your warranty to cover accidental damage and a 50-night trial period to test your base at home.
You can only initiate returns after a 30-day “adjustment period” to allow your body to adapt to the product. While the 30-day rule seems like unnecessary red tape, some adjustable bed owners who participated in our in-house focus group highlighted that it could take a day to a few weeks to determine if the base improved their sleep quality.
While we don’t like that Nectar only offers a short three-year manufacturer’s warranty with your purchase, you can extend your warranty by ten years with full coverage. This is ideal if you have children and pets who love climbing over (and under) your bed. Ten years is still relatively short, but no other brand in this review offers full coverage for this length of time.
We don’t like how Nectar doesn’t currently offer in-home delivery for split king adjustable frames, but they did at one time. A member of the Handbook Team bought their split king Nectar adjustable base three years ago with white glove delivery, and they were glad they did because the base was heavy.
For now, the brand outsources this service to Handy.com, where you can get 10 percent off your appointment (about $100–$200 before the discount). However, we advise you to monitor the job if you use this service. A team member had a negative past experience with a Handy cleaner who came to their apartment, hung out while at work, and didn’t clean anything.
From one of our Nectar testers:
“Overall, I like it. The motor is actually pretty quiet, but when the bed goes up and down, it creaks, especially if it doesn’t have weight on it. For the price, it was a good value.”
DreamCloud: Best Bluetooth-enabled split king adjustable bed
Why DreamCloud is our pick for best Bluetooth-enabled
We chose the DreamCloud adjustable base as our pick for the best bluetooth-enabled adjustable bed because of its easy-to-use, bluetooth-paired mobile app. This base stands out for its advanced features, including a quiet massage function, zero-gravity, anti-snoring, and other presets. Other noteworthy features include USB ports for charge devices, and adjustable height settings. The DreamCloud adjustable bases are covered under their 3-year limited warranty, protecting buyers from manufacturing defects.
Who may like DreamCloud: Since the DreamCloud adjustable base is Bluetooth-enabled and includes USB charging ports, this bed is a good option for anyone who prefers to change their settings using the mobile app instead of a remote.
Who should consider other options: DreamCloud doesn’t offer white glove delivery for split kings, so it isn’t the best choice for someone who needs assistance setting up their new bed.
DreamCloud tester insights
We found the DreamCloud split king adjustable bed and mattresses to be a mid-ranged price option that’s especially ideal for couples looking for extra features like multiple preset positions, 3 different massage intensities, USB ports, and programmable memory, all controlled from the base’s wireless remote or an app on your phone.
DreamCloud’s adjustable split king base takes two twin mattresses. If you choose to top your base with a DreamCloud mattress, you can learn about their different styles in our DreamCloud mattress review. We find DreamCloud’s memory foam mattresses offer a firm feel and support that keeps the sleeper comfortably on top of the mattress. We like this mattress for combination sleepers who prefer to switch positions when they sleep.
DreamCloud’s hybrid and memory foam mattresses also contain cooling gel that helps keep hot sleepers more comfortable at night. A premium in-home setup of two items costs $199, but if you need more (like two mattresses and the base), each additional item costs an extra $49.
We do feel sleepers over 250 pounds may risk sinking into the memory foam mattress more, which may exacerbate issues like back or hip pain. We also find DreamCloud’s mattresses rate low for edge support-how much the mattress maintains its structure and shape on the edge of the mattress-but with a split king, that particular issue may be reduced with the smaller mattress size.
Brooklyn Bedding: Best value split king adjustable bed
Why Brooklyn Bedding is our pick for best value split king adjustable bed
We chose the Brooklyn Bedding adjustable bed as the best value split king adjustable bed because it is a high-quality, affordable base. During testing, we noted the bed’s slim design and how smoothly and quietly it shifts between positions. The base’s high weight capacity and easy, no-tool assembly are also noteworthy. Brooklyn Bedding’s bases include several upgraded features, like USB ports, anti-snore and zero-gravity presets, and a wireless remote.
Who may like Brooklyn Bedding: Since the Brooklyn Bedding adjustable base has an 850-pound weight capacity for each side, it’s a good option for heavier-weight sleepers sharing a bed.
Who should consider other options: Brooklyn Bedding doesn’t currently offer white glove delivery, so it isn’t a good choice for someone who can’t set up the bed themselves.
Brooklyn Bedding tester insights
Our testing finds that Brooklyn Bedding mattresses are mid-range in firmness and edge support, with higher marks for cooling properties. We also find their mattresses ideal for combination and back sleepers because they tend to be softer, allowing for a bit of give as you move. The additional quilt pillow top upgrade provides what our tester said was “a superficial hammock feeling” that “feels nice.” Our tester also commented that Brooklyn Bedding mattresses, in general, seem to strike a “great balance” between support and pressure relief” if you’re looking for a mixture of the two. If you choose the Ultra Adjustable Base with your mattress, you’ll also get three different massage settings.
Shoppers should also note that when you select some of the mattresses from the Brooklyn Bedding website, the option to upgrade with a “cloud pillow top” to each mattress is already selected, so if you don’t want the upgrade, you should select “no” from the dropdown to see the lower price reflected. Additionally, for any of the split king beds, the website instructs you to order two of each mattress to create the split king, so you’ll need to double the price for your final cost.
Brooklyn Bedding’s site advertises the adjustable power base as the “slimmest” on the market. The Ultra version has plenty of extra features, like under-the-bed LED lighting, three massage settings, preset positions, USB charging ports, and the capacity to hold up to 850 pounds per couple.
Sleep Number: Best mattress-base combo for couple customization
Why Sleep Number is our pick for best mattress-base combo for couple customization
We chose the Sleep Number adjustable base as the best mattress-base combo for couple customization because of its highly individualized sleep experience. Couples with completely different sleep preferences can combine a split king base with one of nine different compatible Sleep Number mattresses. Additionally, couples can use the SleepIQ app to make changes to the positioning and firmness of both the mattress and the base. During testing, we noticed the Sleep Number base is quieter than the other beds we’ve tested, so couples sharing the bed won’t disturb one another when they adjust positions throughout the night.
Who may like Sleep Number: Since Sleep Number provides a highly customizable sleep experience for both sides of the bed, we recommend it to couples with different sleep preferences.
Who should consider other options: Remotes are an added expense with a Sleep Number bed, and our testers noted that the remotes are a bit complicated and hard to use. We suggest someone who prefers an easy-to-use remote over a mobile app consider a different option on this list.
Sleep Number tester insights
The Handbook Team chose Sleep Number as the best mattress and adjustable base combination for those who want total control over their sleep preferences without affecting their partner’s comfort. Not only can you adjust your split king positions on either side, but you can also adjust the mattress firmness to your own liking. This is ideal for couples with completely different sleeping needs or if your preferences change occasionally.
We also love how this brand offers a similar variety of split sizes and styles to Saatva, plus an additional FlexTop (split-top) California king size, but we don’t like that they’re about $1,000 more expensive compared to Casper and Serta.
Sleep Number uses unique air chamber mattresses, allowing you to adjust firmness by emptying or filling the chambers at the touch of a button. When our Handbook Team tried this mattress, we could feel the mattress adjusting firmness under our bodies. Sleep Number representatives said your “sleep number” setting is the number that relieves most of the pressure under the hips and shoulders in your preferred sleeping position, which is determined in-store using a pressure mapping system.
From one of our Sleep Number testers:
“My Sleep Number setting was 35, which was softer than I was used to, making it difficult to switch sleep positions because I felt sunken in. But when I was still, it felt comfortable.”
The SleepIQ app lets you control all three Sleep Number bases to adjust mattress firmness and adjustable base position through your phone without a physical remote. This is the only brand that charges you for the remote ($49 each). While we understand the convenience of having the controls on your phone, studies agree you should limit blue light exposure through your phone before bed to improve sleep quality. Forcing users to use their phones before bed or in the middle of the night seems counterintuitive to sleep improvement.
Whether you have a physical or mobile app remote, you and your partner will have control over your own side unless you’re using the Partner Snore feature, which allows you to control your partner’s head elevation to alleviate their snoring, so you both sleep soundly with minimal disturbance.
The app also provides sleep-tracking insights, like how long you slept and how restful it was, by decoding your heart rate and breathing patterns through the mattress’s sensors. This can help you identify settings that improve your sleep patterns. But if you’re truly interested in sleep tracking, the Handbook Team encourages you to consider Tempur-Pedic’s bed and accompanying app instead because of its sleep coaching and smart alarm features.
Handbook Team Tip #2
Sleep Number offers a 20 percent educator discount on purchases, and a customer representative told us that most stores host major holiday promotions. If you’re only looking for head adjustability to address snoring or acid reflux, choose the FlexTop 1 adjustable base over the others and save $1,000–$2,000.
Unfortunately, Sleep Number adjustable bases have no trial period, but the mattresses do. You can try a mattress for 100 nights and return it anytime after the thirty-day adjustment period. Both products have the same 15-year warranty period.
From one of our Sleep Number testers:
I loved having so much control over my bed’s firmness and positioning. It’s easy to make adjustments, and it’s nice knowing that my preferences won’t disturb my partner. However, because I was only shopping for an adjustable base, the customer representative advised us to shop for other brands since Sleep Number beds function best with the Sleep Number mattress. I appreciated the honesty”
Tempur-Pedic: Best advanced technology split king adjustable bed
Why Tempur-Pedic is our pick for best advanced technology
We chose the Tempur-Pedic adjustable base as the best advanced technology because of its impressive lineup of high-tech bases with smart features designed to improve your comfort and sleep quality. For individuals managing sleep apnea or snoring, the Snore ResponseTM feature automatically detects if a sleeper is snoring and adjusts their positioning while they sleep. Additionally, the Tempur-Pedic base includes sleep coaching using AI-powered technology, which tracks sleep metrics to provide adjustments to help improve sleep. Tempur-Pedic adjustable bases can be controlled through a provided, wireless remote or through a Bluetooth connected smart phone app.
Who may like Tempur-Pedic: Since the Tempur-Pedic Snore Response technology adjusts positions while you sleep, this bed is a good option for a couple sharing a bed when one person snores at night.
Who should consider other options: Our tester noticed that under-bed lighting is fairly dim on Tempur-Pedic bases, so those needing extra lighting to safely navigate their room at night may require a different option.
Tempur-Pedic tester insights
Tempur-Pedic offers the most technical adjustable bases on the market. High-tech beds aren’t everyone’s cup of tea, but we enjoyed the extra sleep-tracking benefits of some of these smart bases because they provide insights and suggestions to improve your sleep. According to Carli Streich, LPC, founder and owner of Cognitive Neurofeedback in Colorado Springs, Colorado, improving sleep quality will foster healthy minds and relationships by helping you regulate emotions and communicate better with your partner.
Note: The Ease Power Base is the most basic model without the technical features, but if you’re looking for a simple and more affordable design, go with Casper or Serta instead. Other bases in the Tempur-Pedic lineup gain more features with each upgraded model, as listed above.
Many features are unique, including
- Lumbar support: An adjustable bar that elevates up to 6 inches to provide low back support.
- QuietMode: A trademarked anti-snore preset, elevating up to 12 degrees.
- Snore Response: Snoring is detected through bed vibrations, then the bed raises the head to the QuietMode position.
- Sleep coaching: AI-powered sleep analytics that provides individualized strategies on ways you and your partner can sleep better.
- Smart alarm: A function that uses sleep data to wake you and your partner according to your sleep cycles using natural sounds and vibrations through the base.
- SoundScape Mode: Built-in speakers allow you and your partner to feel your favorite sounds through speakers that vibrate on each side.
- WindDown Program: A cycle of different positions and massage settings to help you relax.
- Smart home connectivity: Bluetooth links your base to your Google Home or Amazon Alexa.
The Smart and ProSmart Bases are the only models that connect to the Sleeptracker-AI app and provide sleep-tracking analytics and coaching. “Sleep tracking can provide valuable insights into sleep patterns and quality, which can lead to significant improvements in sleep, mood, and general well-being. By monitoring factors such as sleep duration, sleep stages, and disturbances, you can identify patterns and potential issues affecting their sleep,” says Streich.
We had a chance to browse the Sleeptracker-AI app with a customer representative at a big-box store. The app was easy to use, and sleep insights were easy to read. But the biggest standout of the Sleep Number SleepIQ app was the sleep coaching and smart alarm features because it does more than analyze your sleep—it provides actionable, individualized ways to improve it.
Handbook Team Tip #3
Tempur-Pedic smart bases sit at a higher price range, but like other brands, frequent holiday promotions drop costs by several hundred dollars.
From one of our Tempur-Pedic testers:
“The adjustable lumbar support bar goes very high. I have a smaller build and was only able to tolerate about one-third to one-half of the height for comfortable low back support. But I think this bar has an additional benefit … I can scoot down the surface and target my upper back for a nice backbend stretch after sitting all day for work.”
Serta: Best trial period in a split king adjustable bed
- 120-night trial
- Free returns
Why Serta is our pick for best trial period in an adjustable bed
We chose Serta for the best trial period in an adjustable bed because this brand offers the longest trial period in the industry. Unlike mattresses, many adjustable bases have a short trial period or don’t offer one at all. Serta stands out for its 120-night trial period, included with all three adjustable base models, and its reputation for being built on free and easy returns. It is worth noting that this trial only applies if you purchase the bed online.
Who may like Serta: Since all Serta adjustable beds include a 120-night trial period, we recommend this option if you are unsure about your decision to buy an adjustable bed and want to trial it before making the commitment.
Who should consider other options: Serta’s split king adjustable beds are California kings, so if you are short on space a different brand may be a better fit for you.
Serta tester insights
Serta is the only brand that offers a 120-night trial on all its adjustable bases when you buy online. Investing in a new bed can be stressful, especially if you’re dealing with chronic pain and want to ensure the bed will help. Opting for brands with long trial periods is a risk-free way to thoroughly test your adjustable base at home before fully committing.
It’s important to note the 120-night trial period and 20-year limited warranty only apply to online purchases through the Serta website. We had trouble finding Serta adjustable beds because they aren’t in many big-box stores, and Serta doesn’t have a showroom. But when we finally located a Serta adjustable base in a Mattress Firm, we were told it came with a three-year full warranty and no trial period. When we called Serta customer service for clarification, an agent told us that retail partners may have different terms. We think this isn’t very clear for shoppers, so if you’re shopping from a third-party retailer, cross-check the price, trial period, and warranty with the brand to ensure you’re receiving the best deal.
Similar to Nectar, Serta encourages buyers to keep their base for a month before initiating a return to allow the body to adjust. If you decide to return it, your process will look different depending on the original delivery service Serta recruits to do the job: RXO Logistics or FedEx deliveries. RXO Logistics is a delivery partner that will call three days after you start your return to schedule a date for removal. FedEx deliveries don’t have a removal process, so you’ll receive guidance on donating your base to a new home.
While the Motion Air model offers one of the most affordable split California king bases on the market at $1,198, it’s also one of the most basic, offering only head and foot adjustability and adjustable height legs. The Motion Essentials model lacks luxury features despite being similarly priced ($1,398) to brands with advanced features, like massage or under-bed lighting. But we loved how whisper-quiet the base sounded in the store, which is great for light sleepers.
What our testers say:
“The Serta Essential Adjustable Base doesn’t have a TV/lounge preset that elevates the head to a fully upright position, but you can adjust it manually to a fully seated position using the remote buttons.”
How we test and choose the best split king adjustable beds
Our Handbook Team visited showrooms and big-box stores to browse like real shoppers, which means we talked to store representatives and tried out each adjustable bed for ourselves. We also vetted brands and models by recording our findings on a 36-question standardized testing form to identify standout features and services, document problems with each product, and describe our shopping experience. For example, we recorded:
- Adjustment speed, noise, and feel.
- Massage modes, intensities, and quality.
- Customer service experience and general satisfaction.
We also surveyed 600 adjustable bed customers and interviewed a focus group of adjustable bed owners to understand their buying experience and how their adjustable base has or hasn’t helped them.
Handbook Team Tip #4
Our survey revealed that 91 percent of users reported they sleep better with their adjustable base, and 73 percent have noticed improved mental health.
For this review, we even brought our significant others along to better understand how salespeople interact with couples as they browse split king options.
From one of our testers
“While most products operate similarly, every brand seemed to offer a different buyer experience online or in-store. Brand transparency and positive interactions with customer service are huge influences on overall satisfaction.”
Our Handbook Team searched for adjustable beds that offered the best fundamentals, like easy adjustability and a user-friendly control system, so all of our options fit the basic features identified as must-haves by survey respondents. But we also considered the functionality and practicality of advanced features, like massage, lighting, and mobile applications, which can offer more convenient ways to relieve pain or wind down before bed.
We found that personal preference determined how useful these features were. For example, some testers didn’t like the massage quality in some adjustable beds because it felt more like an intense vibration rather than a kneading sensation, which you would get with a massage chair. But this is subjective to the person, so you might find the vibrations relaxing, depending on your tolerance.
In order to focus on the adjustable bases themselves, we structured our test designs so they isolated the bases and judged them on criteria independent of the mattress. For example, we tested the capabilities of the adjustable bases, such as positioning options, that are the same no matter what mattress you use. It is important to note that certain criteria like mattress firmness will have an impact on your comfort, but we strategically organized our test designs to focus on the comfort of the adjustable base regardless of what mattress you have.
Lastly, we gathered input from mental health experts, sleep specialists, and psychologists with experience in relationship counseling on how split king adjustable beds can help some couples sleep better together.
Adequate sleep is crucial for maintaining optimal mental health and fostering healthy relationships. It supports emotional regulation, cognitive function, and communication skills, allowing individuals to better navigate and manage their own emotions, as well as engage in meaningful and supportive connections with others.

What is a split king adjustable base?
A split king adjustable base is two twin XL adjustable bases used together with two twin XL mattresses to create one king bed. Because these are fully split beds, sleepers are able to adjust their side of the bed to their specific comfort needs. These beds work well for couples with individual health needs.
Split king vs. king vs. split-top adjustable bases
Unlike a standard king, split king beds are designed as two twin XL adjustable bases so that each partner can adjust their platform to their liking. Since each side moves separately, you’ll need two twin XL mattresses. Split California kings are longer to accommodate taller people, and they require a special type of twin mattress called a California twin or a twin XXL, according to Saatva and Tempur-Pedic representatives. If you and your partner are looking for an adjustable base, this is a good option for individual adjustments, but if you like to cuddle, it’s uncomfortable where the mattress splits.
Some split styles only separate the head of the bed, like the Saatva Upper-Flex and the Sleep Number FlexTop. These beds adjust independently at the head and together at the feet. Couples who only need head adjustability would like this option because it only divides from the shoulders up, keeping the rest of the base whole. But you might learn to like leg adjustments while your partner doesn’t, which means you’ll battle over leg position.
Standard king adjustable beds use one king-size mattress, and both sides of the bed will move as one unit on a single platform. Couples with similar adjustment needs will like this style, but you might need to compromise with your partner over preferences.
Pros and cons of split king adjustable beds
If you think you benefit from a split king adjustable bed, consider the pros and cons before you buy. While the main benefit of individual adjustability seems obvious, you may not have thought of other considerations.
What we like about split king adjustable beds
- Accommodates personal sleep preferences: Each partner gets their own adjustable side and remote, so you won’t disturb each other as you lounge and sleep. Depending on the brand and model, you can sleep on different mattresses.
- Multiple styles and sizes: Split beds typically come in standard king and California king sizes. But if a completely split bed isn’t for you, Saatva and Sleep Number offer split-top options that only split the head.
What we don’t like about split king adjustable beds
- More expensive: King-size adjustable bases, split or not, are more expensive than smaller options. You’ll need to purchase two twin XL mattresses if this is your first split-style bed, which are two extra expenses, plus the right bedding.
- Complicated care: A split king bed is like having two beds. This means changing two sets of bedsheets, making the center mattress corners hard to reach. Note that split-top beds need compatible mattresses with special fitted mattress sheets that fit like a flip-flop. They’re uncommon, so your best bet is shopping for bedding through your bed brand’s website.
Handbook Team Tip #5
A member of the Handbook Team shared that she puts her base into zero-gravity mode when she changes the sheets on her split king adjustable bed, exposing the corners and making the job much easier.
Who would benefit from using a split king adjustable bed?
If you want to personalize your lounging and sleeping position independently from your partner (so you can sleep better throughout the night and improve physical and mental recovery), you may benefit from a split king adjustable bed.
From our adjustable bed focus group
“[My husband] tried it, and it didn’t do anything for him. He just never uses it. I use my side all the time, so I’m glad we got one that was not all together because I don’t know if he would’ve let me keep it.” —Focus group participant
According to Streich, the licensed professional counselor in Colorado, research suggests that sleeping together can support healthy relationships and promote physical closeness and intimacy. “However, it is important to note that individual preferences and sleep quality can vary,” she says. Sleeping together can be important to relationships, but not at the expense of losing sleep. Sleep deprivation is counterproductive, leading to social withdrawal from your friends and partner. “Some couples may find that sleeping on a split king adjustable base, which allows each partner to customize their sleeping position, can be helpful in getting a restful night’s sleep while still maintaining a sense of togetherness.”
Julia Catlin, a licensed psychotherapist at Calm Science in Las Vegas, agrees. “As more and more couples are considering a sleep divorce, modern options like a split king adjustable base can make sleep feel like a luxury while still supporting quality time in your relationship,” she says. “For example, the Scandinavian Method involves using two different blankets to improve intimacy, sleep, and enhance your relationship when partners share the same bed. A split king adjustable base can support this method and offer enhanced results.”
Some people with mobility issues also benefit from adjustable beds, as the head adjustability can help you sit upright, making it easier to get out of bed. Many models in this review also have safety features that help you see at night to reduce tripping hazards, like the under-bed lighting included with the Saatva Adjustable Base Plus. The right bed depends on personal preferences and needs, but if you’re shopping for adjustable beds for seniors, you may want to consider firmness, support, and pressure relief.
Who would not benefit from using a split king adjustable bed?
Our Handbook Team initially thought split king adjustable beds were unnecessary for solo sleepers, and this is true for some. However, after listening to our focus group participants, you may want to consider future partners before purchasing any adjustable bed.
One participant told the group she bought a queen-size adjustable bed just before entering a new relationship. Now, she’s worried her new partner will dislike her new base and the sleeping position she prefers. If you’re single and dating, try temporary solutions with pillows and wedges before committing to any adjustable base, just in case your sleeping situation changes.
While some couples benefit from the split sleeping surface, Streich emphasizes that not all couples will like the accommodation. “If a couple values physical closeness and intimacy during sleep, a split king bed may negatively affect their connection,” she says. Nervous that the divide may threaten intimacy? A good compromise could be a split-top style, like Saatva’s Upper-Flex option, which only divides the head and not the rest of the bed.
We also encourage couples to talk to their doctors before purchasing an adjustable bed as a treatment strategy for a medical condition. Your doctor may not recommend an adjustable base and provide more appropriate solutions. We also encourage you to talk to a couple’s counselor if poor sleep affects your relationship, as they may have specific insight unique to your circumstances.
What to consider when choosing the best split king adjustable base for you
Our Reviews Team chose the Saatva Adjustable Bed as the best split king adjustable base overall, but we also know this option won’t be the right fit for every sleeper. Before choosing an adjustable base, we suggest considering the following considerations.
Split options
Some couples don’t need to divide the entire bed to get the sleep they need but are looking for the ability to elevate the head of the bed to different heights. For example, if one partner snores or has a health condition requiring them to sleep at an incline, while the other partner prefers to sleep flat. For these sleep situations, the split-top styles offered by Saatva and Sleep Number don’t have a large separation between sleeping surfaces.
Mattress compatibility
Split king adjustable beds are not universally compatible with all split king mattresses. Instead, you will find most brands are compatible with a select number of models. In most cases, your brand’s adjustable bed is only compatible with mattresses sold by that brand. Often, they aren’t even compatible with all of the brand’s mattresses, so it is always best to confirm your chosen mattress works with the base you want. If you have any concerns, we suggest contacting the brand’s customer service department to get more information about which mattress will work best with your new bed.
Presets
While it is not true that all adjustable beds come with presets, many do. These are preprogrammed positions that allow you to customize your sleep settings with the press of one button. For example, an anti-snore preset elevates the head of the bed at an angle that is most effective for reducing snoring, while a zero-gravity preset evenly distributes the weight of the body by elevating both the head and the feet. Many beds allow sleepers to create a custom preset and offer a head and foot raise.
Price and warranty
Adjustable beds can be pricey, but there are ways to find a deal and save money on your way to better sleep. Most brands have financing options and many offer discounts and promotions around major holidays.
Not every brand offers a trial period, but the ones that do are important to highlight because they allow you to try the base in your home environment and determine if it’s a good buy. Many focus group participants reported an adjustment period of a few days to a few weeks, but some knew if their new bed was right for them and their partners after the first night.
Advanced adjustable base features
- Massage: According to a Sleep Number store representative, massage was one of the least used features in the brand’s adjustable bases, so they removed it altogether. After trying multiple bases with built-in massage, we understood why: It felt like vibrations more than kneading, which some team members found uncomfortable or annoying. Some research suggests vibrations can improve blood flow. Still, many of these results occur under controlled settings with specific vibration types and frequencies, so it’s unclear if these benefits would apply to adjustable beds. However, you might love the massage settings in adjustable bases like some of our survey respondents, so you should try it before crossing it off your wishlist.
- Wall alignment: Some brands offer wall-aligning or wall-hugging technology, which moves the upper portion of the base closer to the wall as the head of the bed elevates. This keeps you closer to your nightstand during adjustments. Our Handbook Team agrees this feature does keep you closer to the nightstand, but you’ll still need to reach behind you, so it’s not a breakthrough solution.
- Under-bed lighting: We like this feature if you need to see obstacles in the dark, but some of the adjustable beds we tested had dim lighting that might not be bright enough to light up the whole bedroom floor. If you need lighting to make sure you don’t trip over the dog when you head to the bathroom at night, go for a thin surrounding bed frame that allows as much light through as possible.
How much does a split king adjustable bed cost?
The lowest price we found for a split king adjustable bed starts at $745, but there aren’t many options at that price point. On average, most split king adjustable beds are in the $2,000 price range. However, anyone who wants the most luxurious split king adjustable bed on the market can be prepared to spend over $7,000.
Does Medicare pay for split king adjustable bases?
Adjustable beds are considered durable medical equipment, so they can be covered under Medicare Part B. Typically, you can expect to pay your copay while Medicare covers the rest of the cost. To obtain coverage for a split king adjustable base through Medicare, you must first obtain a prescription for the bed from your healthcare provider.
How to save money on split king adjustable beds
If Medicare doesn’t cover your split king adjustable bed, there are other ways to save money on this purchase. While these beds aren’t as heavily discounted as mattresses, many brands mark them down throughout the year. Watch for sales around major holidays, including President’s Day, Memorial Day, Fourth of July, Labor Day, and Black Friday.
Our final verdict
Saatva is the best on the market for its features, reputation, and free in-home delivery service. The brand’s advanced model offers the best features needed for a good night’s sleep without complicated or costly perks. Although Saatva doesn’t offer a trial period, you can exchange your twin XL mattresses for a king-size mattress if you dislike the split style. And where Saatva falls short, Nectar, Serta, and DreamCloud shine, offering trial periods to ensure you and your partner love your base and features before fully committing.
If you’re like 73 percent of adjustable bed users in our survey, you’ll notice improvements in your sleep and mental health. Before shopping for an adjustable bed to address a medical condition, talk to your doctor to ensure your new bed fits your treatment plan.
Frequently asked questions
For sleepers sharing a bed with a partner, a split king adjustable bed is certainly worth it, because these beds can be customized to accommodate both sleepers’ preferences.
Yes, you can feel where the two mattresses meet if you’re situated toward the middle. If you want to test a split king to make sure you and your partner like the feel, we recommend going to a store or purchasing a split king base and compatible mattress with a trial period.
A split king is made up of two twin XL adjustable beds, which are compatible with two twin XL mattresses.
It’s more challenging to change bedsheets on a split king adjustable bed because you’ll have to change each side, and the middle corners are hard to access. A member of the Handbook Team shared that she puts her base into zero-gravity mode to expose the corners, making the job much easier.
