Split King Bed in Bedroom

Buying a mattress is a big investment that will affect your sleep for years to come, which is why it’s so important to make an informed decision. Here’s what you need to know if you’re choosing between a split king and a traditional king mattress.

What is a Split King Bed?

A split king bed is a bed that combines two separate twin XL mattresses to create a combined mattress the size of a traditional king bed (76” x 80”). Split king mattresses are compatible with adjustable base beds and are great for couples with different sleep preferences.

Split King Vs. King Bed

Deciding between a split king and a king mattress? Here’s what you need to consider.

Split King Bed: Pros & Cons

Split king beds have many benefits. For one, because a split king mattress includes two separate mattresses, motion transfer is eliminated. That means that when your partner is tossing and turning, you won’t even notice.

Generally speaking, split king mattresses are the best way to accommodate couples with different sleep preferences. Not only can your half of the bed move separately on an adjustable base, but you can also choose mattresses with different levels of firmness.

One downside of a split king bed is that you’ll need to take extra care when purchasing sheets. While some people end up combining sheet sets so they have two twin XL fitted sheets and a king cover sheet, there are sheet sets specifically designed for split king beds.

Because the mattresses are separate, there is a small gap between the two beds which can cause discomfort if you or your partner tend to drift toward the middle of the bed over the course of the night.

How to Keep Adjustable Split King Mattress Together?

While choosing the right fitted bed frame should alleviate this problem, people who move a lot in their sleep sometimes report that split king mattresses slide apart over the course of the night. If you’re trying to keep your adjustable split king mattress together, you can try one of these solutions.

Adjust the Iron Plate Connector

Many split king beds come with an iron plate connector. If you’re having trouble keeping the mattress together, try resetting the metal plate to the farthest setting apart.

Invest in Non-Slip Accessories

If you’re still having issues, you might want to purchase a non-slip mattress pad or try using non-slip tape on the bottom of your mattress.

What Kind of Sheets Do You Put on a Split King Bed?

A split king mattress requires two fitted twin XL sheets and a king-sized cover sheet. If you’re buying a sheet set, there are specially designed split king sheet sets that include the combination of sheets you need in a wide variety of styles, materials, and colors.
