Split-king mattresses allow you and your bedmate to have your own side of the mattress — in all senses of the word. It’s essentially two twin XL mattresses pushed together, with the option to tailor each to your unique preferences and needs. If you’re looking to level up this already royal sleeping experience, why not consider adding an adjustable base?
“Adjustable bases are also great for helping to maintain proper spinal alignment, especially if you are experiencing pain and discomfort while resting on your back,” says our chief medical advisor, Dr. Raj Dasgupta. His advice, alongside the experience of our sleep experts, helped us figure out what to look for in the best adjustable beds for split-king mattresses.
We’ve tested over a dozen different frames and bases, including split-king versions, to get a feel of what works and what doesn’t. After evaluating these bases for quality, ease of use, and overall sleep enhancement, we gathered our list of favorites down below.
Our Top Pick
The best adjustable bed for a split-king mattress is the Nectar Premier Adjustable Bed Frame, because it has all the frills: massage, underbed lighting, and preset positions for zero-gravity, anti-snoring, TV-watching, and two options to save your favorite memory positions. Our testers thought this bed was fairly straightforward to use in its split-king model, and it comes in at a reasonable price to boot.

What I Looked for in Adjustable Beds for Split King
Adjustable bases are a big investment, so it’s important that you find one that works well for a split-king mattress. Here’s what I honed in on when deciding which frames made the cut:
- Ease of use: Adjustable beds should make sleeping easier and more comfortable, and not require a ton of trial-and-error to figure out. Unfortunately, some manufacturers don’t realize that simpler is better, and trick out their bases to the nines. This can make things more difficult for consumers, so we focused on beds that we felt were straightforward and easy to use. We took a look at the remote design, any preset positions, and how quickly the bed responded to any inputs. We also awarded each bed an overall ease-of-use rating, alongside our final total experience score, each out of 5. You’ll notice that every mattress earned at least 4 out of 5 or higher in each category.
- Features: An adjustable mattress can include everything from pinpoint massage to rave lights underneath. Whether you need that in your sleep hygiene routine is up to you, but our testers made sure to test out all the bases’ tricks before giving our final thoughts. We made sure each feature was accounted for and performed as advertised, explaining how they contributed to the adjustable base experience — and if they were worth their weight in gold. On this list, you’ll find bases that have every bell and whistle you could think of, as well as those more streamlined for adjustability only.
- Noise: As a light sleeper, the slightest out-of-place sound can jolt me out of sleep, let alone the mechanical whirring of an adjustable base. We know that many sleepers experience this same problem. Moreover, when it comes to a split king, there’s a chance that one partner could be maneuvering the base while the other is asleep, so silence becomes paramount. We used both our ears and a decibel-measuring app to see how loud each base got when in operation. No base earned below a 4 out of 5 for overall noise, and some even earned a perfect 5 for some of the quietest adjusting we’ve encountered.

Other Bases Considered
Didn’t like any of the options above? Here are some other bases on the market that might better fit your fancy:
Bear Adjustable Flex Bed
The Bear Adjustable Flex Bed has fully adjustable legs to accommodate a variety of heights, in addition to a zero gravity preset and two customizable presets. Other design touches include a remote flashlight and motors designed to stay quiet while the mattress is adjusting. Unlike several other models on this list, the Bear Mattress Adjustable Flex Bed doesn’t have a massage function. While massage isn’t for everyone, it’s a shame this base doesn’t have it, since a split king-size can run you as much as $1,600 — and it’s currently on final sale, so you can’t reap the benefits of a sleep trial.
Nolah Basic Adjustable Base
The Nolah Basic Adjustable Base is a high-tech base with all the bells and whistles, despite its name. The base comes with a vibrating full-body massage with three intensity levels, plus extra features like underbed lighting and USB ports for charging. The reinforced steel undercarriage also makes this a super sturdy and durable bed frame that can support up to 750 pounds. Just note that a split-king model will run you nearly $1,500, which may not be appealing for folks who don’t need all the frills.
How We Picked and Tested These Bases
Studies show that adjustable bases can actively work to help improve sleep duration and quality through their many enticing features, but they’re not worth the hassle if they don’t work well and without making bedtime more complicated and noisy. This is what I kept in mind as I picked out the best of the best adjustable split-king beds.
Ease of Use
Whether an adjustable base is described as bare bones or super high-tech, you don’t want to spend hours fiddling with remotes or decoding instruction manuals. Getting higher quality sleep should feel intuitive, even with the advancements that adjustable beds can offer.
That’s why we judge every base we use for its ease of use. We even see if we can figure out how to work the adjustable base before seeking out the instructions — truly wicked, I know — to get a feel for its straightforwardness. Can we adjust the head and foot independently from the get go? Does everything move at a reasonable pace, and to the level we expect it to? These are all things that go into our eventual rating out of 5.

Within this realm, we also take a look at the remote’s design and functionality, something we also rate on its own out of 5. These remotes can be pretty tiny, and sometimes the buttons don’t offer much clarity or description. If they’re hard to press, too, that’ll knock some points off. A wireless remote can also offer range of motion — but you’ll also have to contend with it possibly getting lost in the crevices of your bed.
If there’s any application included with the adjustable bed, we’ll investigate that as well. More often than not, these act as a second remote, but it’s important that they’re easy to decode and fully functional — should you encounter the issue I mentioned above.
It’s also important that all the features are easy to access and function as expected. Below, I’ll get deeper into the nitty-gritty of how we evaluate each.
Features
Adjustable bases come in a variety of styles, and some come with high-tech features. Think about what kind of adjustable bed you want and the features you need. Once you know what you want in a base, your search will be easier. I’ll outline some of the features we commonly see in adjustable bases and explain how we test and judge their effectiveness.
Zero Gravity
You may have noticed that many adjustable beds come with a zero gravity preset. Basically, it’s a position that puts your head and legs at very specific angles to simulate a feeling of weightlessness, hence the name “zero gravity.”
NASA invented this position to ease stress on astronauts’ bodies, and it’s now a common preset for adjustable beds. The raised legs and tilted head are meant to support the heart, spine, and nervous system to make it easy to wind down and sleep.
Moreover, some studies claim that this also places less stress on the spine, which may also help folks with spine-related pain or discomfort find relief. “Some senior sleepers might find the zero-gravity position, or the inherent adjustability of an adjustable bed, much more comfortable on any pressure points,” Dr. Dasgupta adds.

Our testers will always try out the zero-gravity preset and give their opinions on how it feels, including whether they notice any pressure relief or discomfort. They even rate their experience for this position out of 5. Note that this preset can vary from base to base, but you can also make small adjustments of your own to find that zero-gravity sweet spot.
TV/Reading Position
Ever try to read a book lying down, and it falls on your face? Or stack a ton of pillows to get just the right angle so there’s no glare on the TV? The upright preset on an adjustable base can help with that.

It’s often called the TV or reading position, and it involves moving the head of the mattress fully upright — so you’re essentially sitting in bed. It sounds simple, but it’s more than effective. It’ll keep you from uncomfortably craning your neck, and when it’s time to go to bed, you can simply lower yourself back down.
This is another position that our testers are always sure to try out and give their opinion. We rate it out of 5, taking into account how far upright the mattress can get us, and whether we think it’d feel uncomfortable after a long period of time.
Anti-Snore
If your partner is keeping you awake at night by sounding like a lawnmower or foghorn, you might want to prescribe them an anti-snore position. Though less common, the anti-snore preset elevates the upper half of the mattress just enough to hopefully open the airways. It might also benefit folks with sleep apnea or acid reflux.
In a split king, it’s especially effective, since your partner can move their side of the bed without disturbing your own. You can each find the perfect position to rest comfortably throughout the night.

Memory Positions
Maybe you don’t like the offered presets and need to make some minor tweaks whenever bedtime rolls around. Instead of oscillating back and forth until you find the right position, many adjustable beds offer the option to program what’s called a “memory position.” It remembers whatever configuration you set it to, and with a push of a button, you’re back to it—no need for readjusting.
In testing memory positions, we’ll take a look at how intuitive it is to set them and reset them, as necessary. Though not all bases offer them, so we don’t have a dedicated scoreset for them.
Massage
A sign of a higher-end adjustable base is one that offers massage settings. How it looks can vary. Many bases offer one general setting with multiple intensities. Others have independent head-and-foot message options. Either way, if you’re looking to wind down with gentle vibrations, it might be worth springing for a premium model.
We’re always sure to test the massage options when available. We want to make sure that you can feel them through the mattress and whether they truly elevate the overall experience.

Noise
If you sleep with a partner, you may be all too familiar with being disturbed at night by their movement. Some people complain that adjustable beds are noisy while they adjust. If your partner adjusts their side of the bed in the middle of the night, you may be woken up by the sound of it moving. Some massaging bases market themselves as having “whisper-quiet” motors but still emit a humming noise while in use, which may disturb some sleepers.

We test how noisy an adjustable base gets using a decibel monitoring application to get an accurate reading for how loud a base truly sounds, not just the humble opinion of our ears. We perform this test while trying out both the zero-gravity and TV positions, recording the highest decibel reading for both. We’d consider close to 30 decibels a truly quiet base.
After rating the noise level out of 5, we’ll also describe if it sounds truly disruptive. Sometimes, a gentle, low-level hum might be soothing, like a white noise machine. But if the noise is higher-pitched or whiny, that might cause more distress, no matter how loud it is.
What Else to Consider
A lot goes into setting up a new adjustable bed system, not just the fancy tech and how easy it is to figure out. If you’re still debating on whether it’s right for you, or caught between multiple options, you might want to consider the following angles in your purchase.
Mattress Compatibility
If you’re buying a new split-king base to work with your existing split-king mattresses, always double-check that they’re adjustable-base compatible. The last thing you want is your bed fighting back from contorting into comfortable positions.
But if you’re purchasing a new mattress, you can look out for this in advance. Latex and foam mattresses are usually the best mattresses for adjustable bases due to their flexible nature. They conform more easily to the changing angles of the base. Many hybrid mattresses are also compatible, but be sure to read the manufacturer’s fine print. It may be more difficult to use an innerspring mattress on an adjustable base because the springs can prevent them from bending.
It can get a bit more complicated when it comes to purchasing a bed for a split-king base. Think of a split-king-size bed as two twin XL beds side by side. Sometimes, a split-king base might even be two independent twin XL bases. The purpose of this type of bed is to have each side operate independently.

However, this means there will also be a space between the two mattresses. Even if you push the mattresses or bases super close together, you may be bothered by the “seam” running down the middle. That’s why you might want to look for a mattress with strong edge support, as it won’t collapse when you roll closer to the middle. If worst comes to worst, you can purchase a “gap filler” that goes under your sheets and may help hide the separation, making snuggle time for couples much easier.
Assembly
The last thing you want to deal with is some IKEA-level witchcraft when setting up your new adjustable base. Thankfully, many companies try to make it easy to assemble their bases, and many tout tool-free setups. Some folks, like those with disabilities or extreme pain, might be physically unable to set up bases on their own. In this case, you might want to check whether the company offers in-home or white-glove delivery, though you might have to pay extra.
We assemble every base that arrives in our studio, so we always make a note if we have any trouble during the process. Though keep in mind that we usually have extra hands on deck!

Size and Aesthetics
Split-king mattresses are large, and adding an adjustable base on top of that can make things tricky when it comes to floor space. So, you’ll want to choose an adjustable base that is able to fit in your bedroom. Some bases can be heavy and bulky, so you may want to look into one with a slim design.
If you want to use the adjustable bed on an existing frame, be sure to check if the base is compatible, since some are only stand-alone. Make sure to double-check dimensions to ensure everything will fit properly, too. The same is true if you’re buying a whole new setup.
You might also want to consider the room’s aesthetics. Some adjustable bases can look fine on their own, but most have a minimalistic feel. A dark-colored steel frame might not match a cottagecore bedframe. Some brands also offer the option to purchase a headboard with your adjustable frame if you don’t already have one.
Price
Adjustable bases can range in price depending on the brand, features, and warranty. The prices in this roundup range from $1,048 to $2,798 for a split-king size. The average price of all these adjustable bases is about $1,690 for a split-king size.
Most brands have frequent sales and discounts offered on their adjustable bases, of which I heartily recommend you take advantage. If you’re worried about taking the plunge on a new base, many also come with extended sleep trials, which allow you to return the base for a full or partial refund if you end up disliking it.
Trial and Warranty
Most companies offer a warranty on their adjustable bases, so they can be replaced if they’re faulty or show unnatural deterioration. The length of the warranty can also be a good indication of quality, as a longer warranty means the company believes its product will hold up for a long time. Most bases only come with a 2- or 3-year limited warranty, but some are longer — like the Saatva Adjustable Base Plus, which has a 15-year warranty.
Though less likely than mattresses, some adjustable bases do come with a sleep trial. This is a period of time, often a few weeks, to get a feel for the product. You pay for the base, but you can exchange it or return it for a full refund, so long as it’s within the trial period.
Sometimes the bulkiness of bases makes them difficult to return, so many brands won’t offer this feature. Be on the lookout for things marked “final sale” — this means no returns or exchanges offered. Always be sure to read the fine print when making your purchase.
