A Guide to Best Split King Adjustable Bed Options

Key Takeaways 

  • A split king adjustable bed offers you, and your partner, flexibility since you can each choose the most ideal sleep position. 
  • Many features such as under-bed lighting, USB ports, and massage settings make adjustable bed bases feel luxurious. 
  • There are health advantages to being able to adjust your bed, such as decreased snoring and improved circulation. 
  • You’ll probably pay more for a split king adjustable bed, but it’s worth it if you both have different sleep needs and habits.
A Guide to Best Split King Adjustable Bed Options

If you share a bed with a partner but have different preferences when it comes to how you sleep, a split-king adjustable bed might be right for you. 

Instead of one large mattress, a split king comes with two extra-large twin mattresses, which are arranged side by side on an adjustable base. This gives both of you a lot of freedom: Each side of the adjustable bed

can be customized to suit each sleeper’s body type and sleep position.

Split king adjustable beds bring significant health benefits. For instance, if one person snores, their head can be elevated, while someone who wants their feet elevated to prevent swelling can do so as well. They’re also quite comfortable for watching TV and lounging in bed. And as with any king-size bed, a split king offers each sleeper plenty of room to move around during the night without disturbing their partner.

Getting a good night’s rest is especially important as we age for many reasons, including brain function. According to a Harvard Medical School study, people who slept fewer than five hours per night were twice as likely to develop dementia. 

A split king adjustable bed could be the solution for couples whose sleep is interrupted by a partner who tosses and turns at night, snores, or simply wants to sit up and read when you don’t. 
Here’s what to look for in best split king adjustable beds, along with top recommended options for when you’re ready to make a purchase.

Saatva Lineal Adjustable Bed Base

We may receive a commission if you click certain product links below. This helps support our independent testing and research to provide free, unbiased product and service reviews for our readers. Learn More about our ad policies.

Pros
  • White-glove delivery and 24/7 customer service

  • Well-designed bed base with a wall-hugging feature and retainer bar to keep the mattress in place

  • Compatible base with many mattresses and bed frames, both from Saatva and other manufacturers

  • Customer service highly reviewed on third-party sites

Cons
  • Returns and exchanges are not available

  • This is a higher-priced option

With the Saatva Lineal Adjustable Bed Base, you may just feel like you’re floating in comfort. This split-king option offers the ability to elevate your head or your feet, take advantage of a variety of massage settings to ease sore muscles or relax, and easily find your way to the restroom late at night thanks to under-bed lighting. The Lineal comes with a remote with a variety of preprogrammed settings. Another perk: The motor is quiet, so you don’t have to worry about waking your partner when adjusting your bed at night. 

The Lineal also has a wall-hugging design, which means that even as you raise and lower the head, the distance between the bed and wall remains the same (so you won’t have to stretch to reach items on your nightstand). 

As with all Saatva products, this adjustable bed comes with white-glove delivery. That means that someone else will take care of the entire initial setup. 

The combination of smart, useful features, along with the white-glove delivery makes the Lineal our overall favorite—it’s the adjustable split-king bed we think most people will appreciate.

What Customers Are Saying

“Very good product and customer service. They really stand behind their product and go out of their way to make sure their customers are satisfied. —Tara R., Better Business Bureau

“I went from an ancient queen Sleep Number on its standard base to a Solaire split king on the lineal base and couldn’t be happier. This is luxury comfort that doesn’t feel like an air bed, except we can independently adjust the firmness. It works perfectly on the adjustable base. I’ve been sleeping in the bed for a full week and haven’t had any back or hip pain, which I had been experiencing nightly for years. So glad we switched!” —CariAnne Behr Huffman, TrustPilot

What Customers Are Saying

“The frame was very quick and easy to put together. It only took about 15 minutes. The price seemed better than most other prices of adjustable frames I had looked at. It seemed to have more features than most other frames. It adjusts very easily. The massage feature works very well. We bought this for my wife who has ALS and can’t move as well now. It is helping her be more independent. We just used our own mattress with the frame and that works very well. This was the cheapest price we could find for it. It was quite a bit cheaper than buying it directly from the maker’s website. I would very much recommend this frame.” —Bill, Amazon

“I ordered a mattress on Nov. 1 and the next day realized the mattress wasn’t going to fit my new place. I went on to their chat to cancel it and because I had a hold on my order, I assumed it was an easy cancellation process. Wrong. 2 weeks later, the order still wasn’t canceled. Connected with them via chat again and they assured me that the cancellation was in their queue and that they sent me a confirmation email for the cancellation. Now Dec. 1, it’s still not refunded and multiple calls to them, they’ve still refused to cancel.” —Julia, TrustPilot

Pros & Cons

Take a look at the pros and cons of the Tempur-Ergo Smart Base: 

Pros
  • Snore response raises the head of the bed automatically when it detects snoring

  • Free white-glove delivery and mattress removal

  • Sleep tracker lets you review your sleep statistics on your phone and there’s sleep coaching through an app

  • Compatible with smart-home products, such as Google Home and Alexa

  • Massage, under-bed lights, USB ports, and zero-gravity features

Cons
  • A pricey option

  • Some smartphone app and smart-home features may be more complex than you require

  • Some complaints related to customer service on third-party sites

Snoring is hard on your sleep, and it also interferes with the quality of your partner’s rest. That’s where the Tempur-Ergo Smart Bases come in: Both the Tempur-Ergo Smart Base and the Tempur-Ergo Extend Base offer a snore response, which raises the head of the bed and can potentially reduce snoring. 

These two bed bases are pricier but also offer more features. All bed bases from Tempur-Pedic offer the ability to lift the head or base of the bed, zero gravity, and a wireless remote. 

What Customers Are Saying

“I love how you can change the height of the top and bottom. Great for people with back problems, acid reflux, and sciatica. The memory foam is great too. The beds have a lifetime warranty! Usually Tempur-Pedic beds last 10 years or more so there is barely any reason to take advantage of it, but it’s good that it’s there just in case. Though definitely worth it, Tempur-Pedic beds are extremely EXPENSIVE. It’s so tempting to get a knock off brand like Bob-O-Pedic because that fits my budget better, but I know they won’t last as long. —Vanessa of NY, Consumer Affairs

“I received the Split King Ergo Smart Twin XL bases and set them up based on the Split Base installation on a Friday evening. Connecting the bases together, as required to allow the Sleeptracker-AI processor to work, fails with the message ‘MISSING CONTROL BOX.’ After calling Tempur-Pedic and being put on hold for over an hour; I was transferred to the company that makes the controllers for their beds vs. them helping me. I ended up having to call back the following day since they closed and wait again for a service tech to answer.” —Raymond of Florida, Consumer Affairs

Pros
  • Relatively affordable

  • Easy setup

  • Compatible with many mattresses and bed frames

Cons
  • Doesn’t have advanced features like massage tools or under-bed lights

It’s a classic conundrum: You don’t want to pay a sky-high price (especially for a nonreturnable product) but you do still want a quality option with sufficient features. If this sounds familiar, you might appreciate the Amerisleep adjustable bed base

The price point for the Amerisleep adjustable bed base is significantly lower than many other options on this list. But you won’t necessarily have to sacrifice features in exchange—this adjustable bed offers the ability to raise and lower your feet and head, a remote, and gravity presets. It’s also compatible with most bed frames and mattresses. 

Take a look at a full review of the Amerisleep Adjustable Bed.

What Customers Are Saying

“The bed is for my 83-year-old mom who had a respiratory incident and needed to sleep elevated. She is more comfortable and likes that her legs can be elevated during sleep to reduce swelling in her foot. She has learned the controls, but I wish the remote had separate colors for massage controls, and separate colors for adjusting the bed controls.” —Yvonne, Amerisleep.com

“This has been a long time coming. Wife and I had a Queen bed for last 14 years. Finally upgraded to a split King with adjustable base. Package had white glove service. It was all worth it!! We now can read in bed without tons of extra pillows to prop us up. We sleep AMAZINGLY!! We have recommended Amerisleep to our friends, and will continue to do so.” —Scott, Amerisleep.com

Pros & Cons

Take a look at the pros and cons of the Sleep Number Flexfit 3 Smart Adjustable Base: 

Pros
  • Tons of useful and luxurious features (from feet warming to raising your partner’s head if they snore)

  • Customizable

Cons
  • Designed to be purchased with a mattress, which ups the price and commitment

What works for one older adult in your bed may not work for the other. That’s why Sleep Number emphasizes personalization in its products. The Flexfit 3 Smart Adjustable Base offers a lot of features aimed at your own specific comforts. For instance, you can raise your partner’s head if they begin snoring in the middle of the night. 

If your feet are frigid, you can take advantage of foot-warming functionality. Plus, you can control the base with your smart device. This Sleep Number adjustable bed also offers other, more standard features seen in adjustable beds, such as the ability to raise your head and feet and under-bed lighting. 

What Customers Are Saying

“From the initial visit to look at beds to purchasing and delivery has been a pleasant experience to say the least! Everyone was compassionate and understanding of our needs and wants. Plus, my husband and I sleep better, wake with less pain, and have more energy!” Amanda W., Better Business Bureau

“We love our split king Sleep number bed. It allows us to adjust the firmness individually. It also lets my husband sleep in a more upright position while I sleep on a flat bed! Changing the sheets is a challenge but once they’re on they’re on! Awesome remote to make changes to the bed firmness and position!” Carol E., Better Business Bureau

Pros & Cons

Here are some of the perks and drawbacks of the Nectar Adjustable Bed Frame: 

Pros
  • Budget-friendly

  • Contains basic features

Cons
  • Does not have under-bed lighting

  • Some complaints related to customer service on third-party sites

As with the Amerisleep Adjustable Bed Base, the Nectar Adjustable Bed Frame is another budget-friendly option, clocking in at $1,298 for a split king. 

If you’re new to adjustable beds, you might also appreciate that this adjustable bed frame can be returned for 50 days after purchase. That’s unusual when it comes to adjustable bed frames, which typically cannot be returned or exchanged. It comes with a three-year warranty, and as with many other adjustable bed frames, the Nectar has a zero-gravity function, USB charging ports, massage features, and a wireless remote control. 

What Customers Are Saying

“Great night’s sleep for the first time in YEARS. I am a side sleeper and often woke with hip pain and pins and needles in my arm/hand. According to my Fitbit, the best nights my sleep score was merely “fair.” Now? No hip pain, no pins and needles, and my sleep score is consistently “good.” —MB, TrustPilot

“I ordered a mattress and received it on time. Unfortunately, I found it to be far too soft for me and wanted to return it after a few nights sleeping on it. I have been trying to contact someone for a week now and I have not been able to get a response from anyone via email or phone. I have sat on hold for half an hour or more trying to get a hold of their returns department. Nothing! I am getting to the point that I am going to contact my card and contest the charges.” —Nick, TrustPilot

How Do Split King Adjustable Beds Work?

The dimensions of a split king are precisely the same as a traditional king-size bed at 76 inches wide by 80 inches long. What makes the split king special is the “split” itself. The bed is really two twin XL mattresses, each measuring 38 inches by 80 inches.

Because of the split feature, your partner and you can choose the position you want—and they don’t have to be the same. 

Here’s how it works: The motorized bed frame moves into various positions at the push of a button. Just about any adjustable bed allows you to raise the head or foot. But in non-split options, that happens simultaneously across the entire bed. With a split adjustable bed, each sleeper has the ability to adjust their side as they see fit. 

Pros and Cons of Split King Adjustable Beds

There’s a lot to love about a split king bed. But they’re not for everyone. For instance, if you sleep solo, there’s likely no need for you to individualize each side of your bed. And split kings are a pricier purchase compared to standard kings. 

Here’s more reasons why you should (or shouldn’t) choose a split king adjustable bed:

Pros
  • More space: Like any king-size bed, a split king is roomy. This can help you get restful, comfortable sleep.

  • Highly customizable: Instead of feeling frustrated by your partner’s snoring or propping up tons of pillows so you can watch TV while your partner drifts off, you can customize your side without bothering anyone else.

  • Sleep undisturbed: By splitting the bed in two, you won’t bother your partner by adjusting your side of the bed. This also means that if your partner is an active sleeper, you won’t be kept awake all night by their tossing and turning.

Cons
  • Significant financial investment: Adjustable beds are more expensive than standard beds, and split adjustable models are even pricier. Plus, unlike other bed purchases (such as mattresses) the bed base is typically nonreturnable.

  • A divide may not be desirable: A split down the middle of the bed may make it difficult to cuddle closely with your partner. Plus, there can be an awkward valley if one person likes an incline and another sleeps flat.

Benefits of Adjustable Bed Frames

The best split king models in adjustable bed frames available offer a variety of benefits: 

  • Increased comfort: Do you enjoy reading or watching TV in bed? If so, you’ll likely appreciate the option to elevate the head of the bed, so you can recline and relax. Plus, massage features in some adjustable beds may boost your comfort—and potentially ease aches and pains. You’ll get more than just comfort with this functionality.
  • Improved health: You’ll get more than just comfort with this functionality. An elevated head also helps to reduce issues with acid reflux, heartburn, and GERD; alleviate breathing issues, snoring, and sleep apnea; improve circulation; reduce edema in the feet and ankles; and help manage lymphatic buildup that develops due to congestive heart failure. Not only is that beneficial to you, but it can help improve your partner’s sleep. (It’s not easy to get a good night’s rest when your partner is making loud noises.)
  • Safety: If an adjustable bed comes with under-bed lighting (or a remote control that doubles as a flashlight) it can help you get to the restroom in the middle of the night without tripping or falling.  

Features to Look for When Shopping for an Adjustable Bed Frame

What is the best split king adjustable bed must-have features list? As you browse the options, consider the below:

  • Massage functionality: First, check that the bed is capable of offering a massage if that’s a feature you value. You’ll also want to confirm the intensity of the massage functionality.
  • Durability: Customer reviews can help you learn more about the life of the bed frame—and how well it stands up to use night after night.
  • Lighting: Many, but not all, of the adjustable bed frames on this list offer under-bed lighting. This can be helpful for middle-of-the-night trips to the restroom.
     
  • USB ports: If the bed has USB charging ports, you’ll both easily be able to charge the small electronics that accumulate on your nightstands (think: cellphones, e-readers, and tablets).
  • Anti-snore adjustments: Some adjustable beds have the ability to adjust—on their own—in response to snoring, while others can be manually set to elevations that might help ward off the sawing logs effect.
  • Warranty or guarantee: Warranties range from a few years to as many as 25 years. Read the policy carefully before purchasing to see what is and isn’t covered. Sometimes, you’ll get one level of coverage in the first year and a different level after several years of owning the bed.
  • Ease of use: Many of these beds boast all sorts of functionality. If you find yourself challenged by the TV remote, complex smart-home features might not be for you. Take a look at reviews again to see how easy it is to set up the bed, adjust it, and use the remote—if there is one.
  • Noise levels: The mechanism that adjusts your new bed will make some noise, but some brands are louder than others. A quieter bed will be helpful if you need to readjust your position in the middle of the night and don’t want to bother your partner while doing so. Check the noise level of the massage function too. A loud sound during a massage may not be restful to you (or your bed partner). 

How Much Do Split King Adjustable Beds Cost?

This is not a low-cost purchase. An adjustable bed frame with split king functionality will typically set you back at least $1,500, and in some cases, it will cost upward of $4,000-$5,000. 

That said, you don’t have to pay for the whole adjustable bed at once. Many manufacturers offer payment plans and financing options. For instance, with GhostBed, you can opt to use Splitit and an existing Visa or MasterCard credit card to split up your payments over up to 12 months, without any interest charges. 

Plus, both GhostBed and Saatva accept payments through Affirm, which allows you to set up a monthly payment plan (with or without APR and interest, depending on the options you select). 

A bed or mattress would only be covered through FSA or HSA if ordered by a doctor to treat a health condition, according to ProBenefits. If you have Medicare Part B, and your doctor orders an adjustable bed for certain specified conditions, some of the cost may be covered. 

Types of Mattresses That Work With Split King Adjustable Beds

In many cases, you’ll be able to use your own mattresses with a split king. Check with the manufacturer first to ensure if they’re compatible. Keep in mind that you’ll need two extra-large twin mattresses (and not a king-sized mattress) to take advantage of the bed’s functionality. 

The same is true for headboards and bed frames as well—most, although not all of them, are compatible with adjustable bed bases. When in doubt, check in with the manufacturer for more details and specifics. 

How Hard Is it to Assemble a Split King Adjustable Bed?

That depends. 

Some manufacturers include white-glove delivery—that’s likely the easiest set-up option, since someone else is dealing with it. Other adjustable beds may require you to get out tools or follow instructions. Generally speaking, the process is not that complicated. 

Where to Buy Split King Adjustable Beds

You have a variety of options to purchase split king adjustable beds, including: 

  • Manufacturer: Go directly to the manufacturer’s website or give them a call to order. 
  • Big box retailers: Many adjustable beds are available through big box retailers such as Costco, or via online retailers like Amazon.
