Sometimes one mattress simply can’t meet the needs of co-sleepers. If that’s the case, a split king adjustable bed may be a good solution.

To create a split king bed, manufacturers place two twin XL beds next to one another, so sleep partners can customize their sleep experience with a mattress that works well for their body type and sleep position. Additionally, since no motion transfers between the beds, couples aren’t bothered by their partner’s movements.

An adjustable split king base adds even more options, allowing users to change the head and foot positions on each side of the adjustable split king independently. Sleepers can raise or lower the bed to reduce snoring, prevent leg swelling, or increase comfort.

We’ll equip you with all the information you need to choose the best split king adjustable bed for you, including discussing our top picks for the best adjustable bed frame for a split king mattress and answering common questions about adjustable beds.

Saatva’s Lineal Adjustable Bed Base has a wide range of position settings to help those with persistent pain. A wall-hugging design also allows for easy adjustments without putting your nightstand out of reach.

Notable Features

Those who enjoy massages in bed are great candidates for the Lineal. The built-in massage function includes head, leg, and full-body settings, each of which has three intensity levels. An under-bed light lets owners safely navigate their bedroom in the dark, and the wireless remote features a built-in flashlight.

The bed’s weight capacity is 850 pounds, which is above-average. The legs can be adjusted in half-inch increments between 8 and 13 inches, ensuring plenty of clearance for people who want extra bedroom storage. A cross-bar at the foot of the bed stabilizes the mattress to prevent slipping.

How It Performed

One notable aspect of the Lineal is volume control. The motor is very quiet, and shouldn’t cause major sleep disturbances for most sleepers. The design is both advanced and easy to use thanks to a user-friendly remote with preset options and sleep wall-hugging capabilities. We also enjoyed the massage function. Each intensity setting is distinct and the gentle, wave-like vibrations excel at pain and pressure relief.

Saatva offers free White Glove delivery for all Lineal orders. This service includes a scheduled delivery date and full assembly in a room of the customer’s choice. While the company does not allow returns for the adjustable bed base, each buyer receives a 25-year warranty with 5 years of full coverage.

The head-up position, also called the TV recline position, makes watching TV or reading in bed more comfortable, while the foot-up position relaxes the lower back and reduces leg swelling. Two USB outlets built into the frame ensure that sleepers can keep their devices close at hand while they’re recharging.

Finally, the adjustable bed’s zoned massage feature creates relaxing vibrations in 15-minute sessions to help induce sleep for those who experience anxiety or tenseness at bedtime. The gentle massage feature can also help reduce joint and muscle pain.

A wireless remote allows you to easily customize the bed to find a setting that is most comfortable. The base has two massage motors located at the head and foot of the bed with three speed settings. The underside of the bed has soft lights, so sleepers getting up in the middle of the night can find their way around the room without disturbing their partner.

The base is easy to assemble, and it includes a headboard attachment for those looking to match the bed to the rest of their furniture. Adjustable legs make it easy for owners to choose the amount of underbed clearance that’s best for them, ranging up to 11.5 inches. Each side features USB ports to easily charge your devices.

How It Performed

Our testing team found the adjustable base’s independent controls make it an excellent choice for couples, especially those with different preferences.

There are also multiple USB ports within reach of the bed’s head area to simplify device recharging.

Lastly, the smart base’s wall glide technology allows for smooth position changes. While moving in gliding mode, the Nolah Adjustable Smart Base takes up as little room as possible and keeps you close to your nightstand.

The two sides of the split king Layla Adjustable Base can be adjusted separately, so couples can choose the head and foot positions best suited to their needs. Each side also has its own programmable wireless remote, making changing positions convenient.

Notable Features

Each side of the split king base includes a wireless, programmable remote that allows users to adjust their side individually. Alternatively, buyers can use the included sync cable to operate both sides simultaneously with one remote.

Both remotes have a zero gravity preset, which is good for those who want to reduce spinal pressure, and a flat preset, as well as three programmable one-touch settings. And with two USB charging ports on each side, sleepers can keep multiple devices handy overnight.

The adjustable bed’s legs are modular, with each leg consisting of four 3-inch sections. By adding or removing leg sections, users can adjust the base’s height between 5 inches and 14 inches.

Shoppers who want more features should consider the Layla Adjustable Plus Base, which is an upgrade to the Layla Adjustable Base. The Plus version includes a head and foot massage delivered by dual-vibrating motors, as well as an anti-snore setting.

The Layla Adjustable Base fits with most headboards, footboards, and rails, so it should be compatible with your existing bedroom furniture. It’s also compatible with most twin XL mattresses.

How It Performed

The Layla Adjustable Base is reasonably affordable compared to similar models and includes useful features that add convenience. For example, the base has USB ports that are easily accessible to both users and two programmable remotes, so each person can adjust the bed with one touch.

Sleepers with persistent aches and pains can benefit from an adjustable bed with a zero gravity setting to reduce pressure buildup. The Helix Adjustable Base features a zero-gravity preset and a built-in massage function with three intensity levels for pressure relief at the touch of a button.

Notable Features

The head and foot of the base are fully adjustable, and the split king and California king sizes allow you and your partner to customize your sleeping position individually. The 4-in-1 stackable legs let you adjust the height of the bed to your preference in 3-inch increments. A retainer bar at the bottom of the frame prevents your mattress from slipping while changing your position. The base has a weight capacity of 750 pounds.

How It Performed

We appreciated the adjustable height, which should appeal to many different sleepers. People with mobility issues getting in and out of bed may prefer the lower profile. Meanwhile, the higher profile is great for people looking for under-bed storage space. Assembly was quick but took more than one person to complete.

Along with the competitive price-point, Helix ships free to customers in all 50 states. The Adjustable Base is backed by a 20-year warranty that protects against structural defects.

Notable Features

The Leesa Adjustable Base has a frame made from sturdy birch wood and black powder-coated steel. Polypropylene upholstery wraps the wood and metal frame, while a patented MicroHook system prevents your mattress from sliding off the base.

Those who purchase the split king size can adjust each side independently, or opt to sync the sides together so they move as one unit. This feature is particularly helpful if you already have a king size bed frame, since you won’t have to purchase a new one to use the base.

USB ports below each side of the bed allow for easy overnight charging, while the massage feature helps you relax. LED lighting beneath the bed helps you navigate your bedroom in the dark, and the remote has a built-in flashlight.

How It Performed

Thanks to its strong and long-lasting materials, our testers were impressed with how sturdy and stable the Leesa Adjustable Base felt. The wide range of motion allowed us to adjust the head and foot to a variety of positions, including zero gravity. We also recommend the base if you need under-bed storage space, as the legs adjust up to 15 inches tall.

Leesa ships the Adjustable Base for free to customers in all 50 states. Your purchase includes a 30-night sleep trial and a 25-year limited warranty.


Why You Should Trust Us

Our expertise spans a variety of sleep topics and products, including adjustable beds. To create this list, our diverse team of sleep experts evaluated a wide variety of adjustable beds.

When testing adjustable beds, we consider many factors, including durability, availability and usefulness of features, ease of use, and pricing. To provide well-rounded and complete reviews, we ensure our testers have different body types and sleep preferences.

How to Choose a Split King Adjustable Bed

When choosing a split king adjustable bed, there are a few important factors to consider. Do you have two compatible twin XL mattresses to use with a split king base? If not, you’ll need to purchase them.

You’ll also need to consider the adjustable bed’s weight limit, assembly, your budget, and the warranty. The trial period may also be a factor in your decision.

What to Look for in an Adjustable Bed

While mattress shopping, be wary of advertisements referring to an adjustable bed as “perfect for any sleeper” or “the best on the market.” Instead, look for more concrete information about your potential purchase, including mattress compatibility, weight limit, assembly, price, and warranties.

Mattress Compatibility

Split king adjustable beds consist of two twin XL mattresses. Most twin XL mattresses are designed to work with adjustable beds. However, some bed types bend more readily than others, which is crucial to adjustability. We recommend using latex, memory foam, or hybrid mattresses because they’re typically the most flexible. If you plan to use mattresses you already own, make sure your adjustable bed can accommodate them.

Weight Limit

Refer to the weight limit before purchasing an adjustable bed to ensure that it’s strong enough for your needs. Remember to factor in both mattress weight and body weight. While most well-built adjustable beds can easily handle several hundred pounds, lower-end frames may be constructed with lightweight materials that aren’t as sturdy.


Some adjustable bed models are more difficult to assemble than others. Mattress companies often recommend that at least two people assemble a base, due to its weight. Those who don’t want to assemble the bed themselves should consider buying from a company that includes White Glove delivery, which means they’ll set it up for you.


The price for an adjustable bed typically falls somewhere between $1,000 and $3,000. However, some luxury models may have a higher price tag. Generally, the price is related to the materials used and the features included. Many retailers offer third-party financing for eligible shoppers concerned about paying the full price upfront.


While many adjustable beds don’t include sleep trials, most of them do come with a warranty. Warranties for adjustable beds vary widely in length and coverage, especially for beds that have separate warranties for electrical components. Be sure to read the warranty details to familiarize yourself with the claim process before purchasing an adjustable base.

Problems with Split King Adjustable Beds

A split king adjustable bed can be beneficial to sleepers and couples in a number of ways, but there are a few disadvantages to keep in mind about these beds. Potential drawbacks for owners include:

  • Expensive pricing: Split king mattresses tend to be more expensive than standard king size models, and the same holds true for adjustable beds. You may spend hundreds, if not thousands, of dollars more for a split king bed compared to a standard king.
  • Limited availability: Many leading mattress manufacturers sell their models in split king designs, but this option is still somewhat rare compared to the six standard mattress sizes. Your ideal mattress may not be available in a split king, forcing you to settle for a less suitable model.
  • Excessively large dimensions: Some bedrooms simply aren’t big enough to accommodate a split king adjustable bed. Make sure to measure the length and width of your bedroom’s floor space to ensure this size will fit.
  • Additional bedding needed: You’ll need to invest in two sheet sets, one for each mattress. Twin XL size sheet sets are fairly common, but not as widely available as king size sets.
  • Uneven sleep surface: Split kings have seams or trenches separating the two individual mattresses. This can make the mattress feel slightly uneven. Mattresses that are not properly anchored to their bed frame can move further apart when you or your partner move at night.

Split King vs. King Adjustable Beds

A king adjustable bed uses one king size mattress, while a split king adjustable bed uses two twin XL mattresses. This means that when you change a king size adjustable bed’s position, the entire bed moves.

The split king adjustable bed, however, uses two different mattresses and operates independently on each side, so sleep partners can customize the position, firmness level, and feel of their side of the mattress without affecting the other sleeper.

Bed Type Split King Adjustable Bed King Adjustable Bed
Benefits Each person gets to choose their own mattress and customize their sleep experience. Couples can operate each side of the bed separately, changing positions and settings one side at a time. With a king adjustable bed, couples can change the position of a single, king size mattress to match both of their sleep preferences. Additionally, there’s no seam between the couple because it’s one bed.
  • Personalized mattress choices and adjustments make for a good night’s sleep for each person, regardless of different preferences
  • A user can enjoy a massage, reduce snoring, or read in a sitting position without bothering their partner
  • With separate mattresses, motion doesn’t transfer when one partner sleeps restlessly or gets into or out of bed
  • Only one king size sheet set is needed
  • With one king size mattress, there’s plenty of room and no seam between the couple
  • Some couples may prefer one mattress rather than two when it comes to sex
  • Each mattress needs its own sheet set, and sheets for twin XLs are more difficult to find than standard king size sheets
  • The seam where the mattresses meet may irritate some couples
  • If the two mattresses aren’t properly secured, they can move apart, creating a gap
  • A single king mattress is more difficult to move than two twin XL mattresses
  • Sleep partners must change the adjustable bed’s position and use features, like massage settings, together
  • Motion may transfer across a king size bed’s surface, which can disrupt sleep

Optimize Your Experience

Because a split king bed is made up of two mattresses, people using it can enjoy an ergonomically designed bed made for their body type and preferred sleep position without worrying about potentially depriving a partner with different needs of a good night’s sleep.

Many split adjustable beds also come with unique features like anti-snore and zero gravity positions or USB ports for charging phones and tablets.

Tailor Each Mattress to Fit Individual Needs

Oftentimes, partners need different things from their beds, and couples can fine–tune a split adjustable bed just for them. For example, one person could be a side sleeper who needs more cushioning around the shoulders and hips, while their partner may be a stomach sleeper who requires a firmer feel to avoid sinking into the mattress at the midsection. In that case, the side sleeper could use a soft mattress topper or even a softer mattress on their side of the split king.

Luxury Features

Those seeking a split king adjustable bed have a variety of features to choose from, including programmable remote controls, silent motors, under-bed lights, and zero gravity settings. Some beds can even sync with a smartphone to provide biometric data and other information to sleepers, coaching them on how to get a good night’s sleep.

Frequently Asked Questions

  • Can you use your existing king bed frame?

    You can find split adjustable beds to fit inside most existing bed frames. However, it really depends on the adjustable bed you choose. Some split adjustable beds are sold as standalone frames, and others work with existing bed frames, though some assembly may be required. For example, some models include brackets for mounting a headboard or a removable platform for placing the bed directly on top of the slats of the frame.

  • Do you need to buy new sheets?

    Unless you already have two twin XL sheet sets, you’ll need to buy some. Because the two beds move separately, regular king size sheets won’t suffice.

    Usually, sheets for your split adjustable king will include elastic or straps that keep the sheet from sliding. While each mattress needs its own fitted sheet, sleepers can use a single top sheet if they choose to.

  • How do you keep a split king adjustable bed together?

    Because the split king consists of two twin XL mattresses, it’s possible for them to slide away from each other during the night when not properly secured. A non-slip pad can help with this by attaching to the base of the mattress to prevent sliding. Mattress suspenders can also be used to hold your twin XL mattresses together. These attach to the bottom of the mattresses, and the pressure pulls them together.

  • Are couples still able to cuddle?

    Yes, couples can cuddle on an adjustable bed. While a split adjustable bed does have a seam, it shouldn’t cause a significant gap between partners. The differences between the two sides of the bed, including their firmness and feel, aren’t likely to cause any significant difficulties, either.

    And even though the split king has two mattresses, you can still use a single comforter and top sheet.
