• Split king adjustable beds consist of two adjustable bases joined together side by side with two twin XL mattresses.
• Each half of the base has a dedicated remote control sleepers can use to control their half of the bed.
• Split king adjustable beds vary in price and features, but there are affordable options with long-term warranties, trials, and discounts.

A split king adjustable bed, where each side may be adjusted independently, is a popular option for couples who have different sleep preferences. Unlike a standard king-size adjustable base, a split king adjustable base consists of two twin XL bases joined together, allowing each side to be adjusted independently of each other, whether that’s for sleeping, reading, working, watching TV, or eating.

Most manufacturers sell split adjustable beds in two sizes: king and California king. While a regular king bed averages 80 inches long by 76 inches wide, a California king is typically 84 inches long by 72 inches wide, depending on the manufacturer.

Because there are two separate mattresses, split king beds tend to provide less sleep interruption when a sleep partner moves, compared with a bed that has one shared mattress. While there are various options to choose from, our Reviews Team narrowed our top picks down to five, taking into account the value, features, sleeping positions, ease of use, and more to help you choose the best split king adjustable bed for your needs. You can also read our review of the best adjustable beds for more options.

• Best Overall: Saatva Adjustable Base Plus
• Most Advanced: Tempur-Pedic Ergo Smart Base
• Best Value: Puffy Adjustable Base
• Simplest Design: Purple Ascent Adjustable Base

* Prices as of January 2023, excluding promotions and discounts

The Saatva Adjustable Base Plus is our pick for best overall split king adjustable bed.

Price: $2,598 (does not include price of mattresses)

Payment options: American Express, Discover, Mastercard, Visa, Google Pay, PayPal, and Affirm

Trial period: None

Warranty: 25-year

Dimensions:

• 80 inches long by 76 inches wide

Weight capacity: 850 pounds for each twin XL base, including the weight of the mattress (Saatva twin XL mattresses weigh between 62–95 pounds)

After taking into consideration price, features, delivery, warranty, manufacturer reputation, and customer reviews, our Reviews Team gave the Saatva Adjustable Base Plus the designation of “Best Overall” in split king adjustable beds. It comes in a regular king size or a California king size, to suit taller sleepers. Each side functions independently and includes all of the following features:

• Five preset buttons: zero-gravity, anti-snore, flat, maximum head height position, and custom
• Safety lock
• Wall-hugging feature that keeps nightstands within reach
• Full-body, head, or leg massage with three-speed options and 15-minute timer
• Under-bed lighting plus a built-in flashlight on the remote

Like many adjustable bed bases, this Saatva base has a zero-gravity setting, which is achieved by lying on your back and raising your legs and head just above the level of your heart. It places your body in a position that mimics the state of complete weightlessness and gives you the sensation of floating.

The Saatva split king adjustable base has a zero-clearance design that allows the base to be used either without legs on a platform bed frame or with adjustable legs. If used with adjustable legs, you can adjust the base height from 13–18 inches.

Saatva provides free white glove delivery, meaning its team members will deliver and set up the bed for you. They will remove the packaging and even remove your old mattress and box spring free of charge. The 25-year warranty consists of a 5-year full warranty followed by another 20 years of limited warranty. Saatva does not accept returns on adjustable bed frames, so all sales are final.

People may prefer adjustable beds for a number of reasons. Studies have shown that the use of an adjustable bed system can result in a reduction in pain severity for those with mild to moderate lower back pain.¹ Adjustable beds have also been shown to help reduce snoring and increase the time spent in deep sleep when users sleep in an inclined position.² People with limited mobility may also appreciate an adjustable bed for greater ease getting in and out of bed by elevating the head of the bed or lowering the foot of the bed. And since you can operate each of the two split king mattresses individually, you won’t disturb your partner when changing positions or getting in and out of bed.

Split king adjustable beds are not for everyone. For example, a split king adjustable base is not recommended for a king-size mattress. If you do use a king-size mattress on a split king base, you have to make sure that each half of the split king base can be joined to operate together when adjusting the position of the bed. If not, you won’t be able to adjust either of the split king bases without damaging the single king-size mattress. Make sure you purchase the appropriate adjustable base for your mattress.

Lastly, split king adjustable beds aren’t ideal for sleepers who like to position themselves in the middle of the bed. That’s because split king mattresses aren’t joined together, so there is a noticeable seam where the two mattresses meet, which can be uncomfortable to sleep on.

Budget

Adjustable bed bases can be quite expensive, with costs ranging from around $1,400–$5,000. If your current mattress is not compatible, you’ll also have to consider the cost of a new mattress in addition to the base. Some companies offer financing options, allowing you a bit of flexibility around price. You may also be able to get a discount for purchasing the split-king adjustable base with the two twin XL mattresses at the same time.

Features

Some adjustable beds are more technologically advanced than others, including features such as a mobile app and smart sensors that monitor your sleep patterns. When choosing an adjustable bed, consider how many of these features you actually need and whether you’re comfortable using the technology. Keep in mind that more tech features tend to raise the cost, so if these aren’t important to you, you’ll save some money by going with more basic models, such as the Purple Ascent Adjustable Base.

For people with limited mobility, one feature deserving special consideration is adjustable-height legs. Adjustable legs on the base allow you to position your bed at the right height for ease of entry and exit, reducing the chance of falls or straining.

Weight Limit

Adjustable beds have a weight limit, typically between 400 and 850 pounds per twin XL base. Keep in mind that this includes the weight of the mattress, as well as anyone sleeping on it. A twin XL mattress typically weighs between 30 and 105 pounds. Before purchasing an adjustable bed, make sure it supports the total combined weight.

Assembly

Some adjustable bed manufacturers offer white glove delivery, which means a professional will carry it in and assemble it for you. Without white glove delivery, it may take multiple people to carry each of the split king bases inside, which may weigh close to 100 lbs each, depending on the brand. Make sure you feel comfortable, or have assistance, moving any heavy boxes and assembling the adjustable base if you order from a brand that doesn’t offer white glove delivery services.

Warranty and trial Period

Most adjustable beds come with a warranty, but they can vary greatly by manufacturer, from as little as three years up to a full lifetime warranty. When shopping for an adjustable bed, read through the warranty to make sure you feel comfortable with the coverage. Consider the return policy, too. Most adjustable beds are final sale, but there are some returnable options, such as the Puffy Adjustable Base, that come with an at-home sleep trial.

Whether you prefer a regular king adjustable bed vs a split king adjustable bed will depend on whether you sleep alone or with a partner. The overall size of the bed is the same, but the split king is split into two twin XL bases and mattresses that can function independently, whereas the regular king base uses one mattress and adjusts as one unit. Those sleeping alone may prefer a regular king, while those with a partner may prefer a split king so they can each adjust their sides of the bed independently.

Split king adjustable beds are a great option for adults who share a bed with a sleeping partner. They may provide relief from back pain, reduce snoring, and offer a better night’s sleep overall. In addition, a split king bed has two separate mattresses so that sleepers are not as bothered by the movements of their sleep partners.

If you’re tech-savvy and prefer a split king adjustable bed with advanced features, consider the Tempur-Pedic Ergo Smart Base. If you want the most basic design with an easy-to-use remote, go with the Purple Ascent Adjustable Base.

If you want to make sure you like your bed before committing to it, consider the Puffy Adjustable Base, which has a 101-night trial and a lifetime warranty. For an all-around solid choice at a reasonable price, our Reviews Team recommends the Saatva Adjustable Base Plus that comes with free delivery and assembly.
