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.

Why It’s Best Overall

The Amerisleep Adjustable Bed Base helps couples create their optimal sleep experience, even when they have different needs and preferences. Designed with quality materials, including industrial-grade steel supports, sleepers can easily alter this durable bed base’s height and position.

The base includes removable legs that can be adjusted between 3 inches, 6 inches, and 9 inches. The Amerisleep Adjustable Bed Base works as a standalone base or with any bed frame.

Notable Features

This adjustable bed base includes a programmable, backlit wireless remote that makes it easy to change the angle of the bed at either the head or feet. The upper body lift angle can be adjusted up to 60 degrees, and the lower body lift angle can be adjusted 40 degrees. Once you find a position you like, you can save it on the remote to revisit it. The remote also includes flat and zero gravity presets.

The zero gravity position creates a weightless feel, alleviating pressure on the body, especially in the lumbar area. The reduced pressure experienced in a zero gravity position can relieve back pain. Zero gravity settings are also designed to increase circulation and oxygen intake.

Lastly, an exceptionally quiet motor enables sleepers to adjust their side of the bed without waking their partner.

How It Performed

With a durable and versatile construction, the Amerisleep Adjustable Bed Base performs better than most competing adjustable beds. Its zero-clearance design means it can be used on a platform or slatted foundation. It can also be used directly on the floor.

Buyers within the continental U.S. receive free FedEx shipping. The adjustable base is easy to assemble but heavy, so setup may require more than one person. The Amerisleep Adjustable Bed Base comes with a 10-year limited warranty.

While many adjustable bed frames come at a hefty cost, the Nectar Adjustable Bed Frame offers a range of useful, and even luxury, features at a budget-friendly price.

Notable Features

The Nectar Adjustable Bed Frame lets couples adjust each side of the bed separately, choosing a position or setting that best suits their sleep style. Buyers can change the bed’s head and foot positions or activate the massage or zero gravity setting using the frame’s programmable wireless remote.

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.

How It Performed

The zoned massage and zero gravity features in the Nectar Adjustable Bed Frame make it a good option for people who want to alleviate pressure, relieve pain, and relax. The adjustable split king bed’s relatively low price-point also recommends it to value seekers.

Free ground shipping is included for buyers within the contiguous U.S. Shoppers also receive a 50-night home trial. If the adjustable bed is returned within 50 days, the company issues a full refund. A 3-year warranty covers defects in materials or workmanship.

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.

Assembly

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.

Price

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.

Warranty

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.

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.
Pros
  • 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
Cons
  • 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 size 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.
