Visibly, there's just one bed — but secretly, underneath those covers, there are two perfect mattresses—one for each of you. It's undeniable that, with a split bed, you have tremendous potential to achieve maximum comfort through customizable positioning, providing a better sleep experience tailored to each sleeper's unique preferences.
Keep reading for sleep expert insight on how you can truly reclaim your side of the bed with a split king mattress. Better yet, feel liberated by personalized positions that will help you regain comfort and sleep better while remaining close to your partner with a split king adjustable bed system.
What Exactly is a Split King Bed?
A split King and a regular King mattress both have the same total dimensions— 76 inches by 80 inches. A split King bed is composed of two Twin XL mattresses and bed bases side by side— each measuring 38 inches by 80 inches. Having two mattresses allows for greater versatility in positioning with an adjustable bed and a more personalized choice for mattress firmness, also known as comfort level, on your side of the bed. For example—one sleeper can choose a medium hybrid for one side, and the other sleeper will still have the freedom to select a soft, all-foam option, like the Gel Max 12'' mattress. Just remember, the height of the mattress and bed base will affect how the beds line up when they're set up next to each other.
King beds, including split King, are not necessarily recommended for bedrooms smaller than 12 feet by 12 feet. Even though the mattress and bed may fit, smaller bedrooms may not accommodate additional furniture, such as two nightstands and a chest or dresser, in addition to the King bed.
Who is a Split King Bed Ideal For?
Split King beds are one of the best options to help sleeper(s) regain versatility and personalization for their mattress. Split beds are highly recommended for couples who have opposite sleep schedules, varying temperature preferences, or other sleep-related needs that differ from those of their partner.
Split beds are also fantastic for anyone who expects to lessen disruptions from motion transfer. For instance, motion transfer may cause you to wake up when someone else gets in or out of or changes positions on the opposite side of the bed.
An Ideal Mattress for a Split King Bed is Flexible & Durable
A key consideration with split king beds is that they are often paired with a split King adjustable bed base. In this case, your choice of split King mattresses should be those composed of flexible support systems and pliable layers to avoid premature or unwanted wear. Today, there are numerous mattress and adjustable bed combinations to cater to the diverse needs of sleepers everywhere.
The Bed Tech Sleep Experts refer to these mattress and adjustable bed combos as sleep systems, including the split King bed.
The extensive mattress selection available today can help you find the ideal fit for your body type and other needs. Still, the choices of styles and brands can lead to uncertainty when trying to decide on the right one for you and your partner. The good news is that long-standing brands like Bed Tech offer only compatible, comfortable mattresses that naturally work well with adjustable beds—due to their durable, flexible design, which is specifically developed for use with adjustable beds.
Don't we all wish there were a straightforward approach to deciding on a new mattress? With split King options, you can choose two mattresses, making it easier than ever to create the best sleep system for you.
The Best Mattresses for a Split King Bed Offer Size Variations
The split King isn't the only intriguing and innovative bed size out there today, and what most shoppers don't realize is that fully split King mattresses aren't even the latest creation. Make sure to check out partially split mattresses, also known as split-head.
Split King Mattresses
A split King bed is composed of two Twin XL mattresses that together form the entire dimensions of a King-size bed, 76 inches by 80 inches. The King-size bed, especially with split mattresses, allows you to have independent positioning and share the bed more comfortably without compromising on aspects that affect your sleep quality or wind-down routine.

The Split Head Queen & Split Head King Variety
If split King beds and mattresses intrigue you, but you don't like the idea of a split or 'crack' down the middle, turn your attention to the split head size variation. Split-head mattresses, primarily available in Queen and King sizes, offer dual adjustability and versatility, allowing lifting and lowering of the head or foot of the bed with an adjustable base. The difference is that split-head sizes preserve the 'cuddle zone'— they don't have a split down the entire middle.
Instead, with a split-head Queen or King, the mattress is one piece, and the separation is only along the top-middle portion of the mattress. The split can be found near the head of the bed, extending approximately 30 inches down, but not the full length of the mattress. With a two-piece split adjustable bed underneath, you'll still be able to adjust the split head size for personalized positioning by lifting or lowering the head or foot of the bed. Additionally, with split and split-head sizes, one sleeper can initiate massage mode from the adjustable base. At the same time, the person on the other side can bypass it by leaving off the massage vibration feature.

With either the split-head Queen or King size, you can preserve the mattress's 'cuddle zone,' making it more inviting to lounge or relax directly across or in the middle of the bed rather than on a mattress with a full split down the middle.
California King Options
Are you or your partner at or around 6 feet tall? For tall individuals, the California king-size bed is often the ideal option to accommodate their needs for extra legroom. Additionally, this size accommodates narrow bedrooms, especially if you want to fit your furniture in as well.

Hybrid Mattresses: A Savvy Choice for Split Bed Sleep Systems
As you research and shop for new mattress options available today, hybrid mattresses have become the go-to style of bed due to their benefits of combining the best of both types—supportive innerspring and adaptable foam or latex mattresses.
Next, why are hybrid mattresses ideal for a split King bed? Their pliability, durability, and overall flexible structure make hybrids one of the best choices, especially when paired with an adjustable bed, creating a sleep system. After setting them up, hybrid mattresses also line up nicely compared to 'fluffier' pillowtop-style mattresses when placed next to each other to create a split King bed.
Hybrids offer high-performance capabilities thanks to the use of strong and sturdy independent coils, as well as comfort layers that often exhibit good longevity. However, be cautious, as not all comfort materials, such as memory foam or latex, are created equally. Bed Tech Hybrid mattresses are crafted with attention to even the most minor details—such as reinforced edge support—and they'll withstand the movements of the adjustable bed frame with ease.
So, Hybrid to be, or Hybrid not to be, that is the next question for you!
The Bed Tech Sleep Experts suggest the answer is Yes!

Flexibility At Its Finest: Resilient All-Foam Mattress Options for Split Adjustable Beds
More evidently, foam mattresses are ideal for a split King bed due to their ability to bend easily and 'line up' nicely when set up side by side. Also, all-foam mattresses by Bed Tech are enhanced with cooling materials and temperature-balancing fabrics to lessen disruptions from feeling too hot or too cold while you sleep.
Another perk of choosing a resilient Bed Tech foam mattress is that they are generally easier to move and often weigh less compared to hybrid varieties with steel coils inside, which add weight to the mattress. Not all hybrids are heavier than all-foam beds, but in this instance and many others, this statement rings true.
