If you’ve ever been browsing for a new mattress, chances are you’ve seen the size option of a split king. You might have wondered: what the heck is that? Here we will define what a split king bed is and help you decide if it is right for you.
A split king size mattress is essentially two twin XL size mattresses combined together side-by-side on separate mattress foundations to equal the surface area of a king mattress size. Split king mattresses are ideal for couples with specific individual needs and preferences, along with people who frequently move and will have to transport their mattress.

Typically, split king adjustable beds work best for couples or people who sleep in the same bed. Each person gets their own personal space and you don’t have to compromise on key mattress factors.
Additionally, there is little risk of motion transfer when the person you share a bed with moves in their sleep or gets up in the middle of the night to use the restroom. This way couples can sleep undisturbed.
It’s time to lay out exactly what the best and worst aspects of buying a split king are for easy decision making.
What type of bed frame works with a split king bed?
Split king mattresses can be used on adjustable bed frames specifically designed for two beds. Each side can be adjusted to separate levels of elevation, and sometimes other sleep settings like firmness and temperature. Split king beds on split foundations are a great choice for couples.
What type of sheets fit on a split king bed?
Split king beds do require a special set of sheets. Split king sheets consist of a single top bed sheet that covers both mattresses, as well as two fitted sheets that will cover each of the twin XL mattresses. Luckily, because of the convenience of split king mattresses, many dual sheet sets are sold in stores.
Can you use a duvet or comforter on a split king bed?
When it comes to outfitting split mattresses with a duvet or comforter, you have two options. You can either get one blanket that covers the entire sleep surface to share, or you can do as the Scandinavians do and sleep with separate twin XL size comforters or duvets.
How do you put a mattress topper on a split king bed?
If you’re interested in adding a mattress topper or pad to either or both sides of a split king bed, you can purchase one in a twin XL size since that is the size of each half of the mattress.
Split king adjustable beds are a great investment when you share a sleep space: each person gets a personalized night of sleep every night. But if you’re not so sure, don’t worry. Most mattress companies give you at least three months to sleep on the mattress risk-free. Take the plunge: you and your partner may never turn back.
