Is a Split King Mattress Right For Me?

A split king mattress is the same size as a traditional king, but actually refers to 2 twin XL mattresses placed side by side. This makes it the perfect companion for an adjustable base, as co-sleepers with different comfort preferences can customize each side of the bed. You can also sync both bases to one remote so that it functions as one unit.

Consider a split king size mattress for...

Large master bedrooms:

The recommended room size for a king bed starts at 12x12, depending on how much additional furniture you have.

Couples:

With its large size, a king mattress is a top choice for couples who want the option to snuggle OR spread out.

Extra companions:

Invite a child or pet to snooze with you, without sacrificing too much space or comfort.

What Are the Dimensions of a Split King Mattress?

A split king mattress is made up of 2 twin XLs, each at 80 inches long and 38 inches wide. When placed side by side, the total sleeping area is 80 inches long and 76 inches wide, the same as a traditional king mattress.
