Twin XL Mattress

Twin XL Mattress Size

The Leesa Twin XL mattress is five inches longer than a standard twin mattress, which makes it the perfect solution for adults sleeping in smaller bedrooms. And as the standard mattress size for most colleges and universities, the Leesa Twin XL is an excellent upgrade for college-bound students.

Full Mattress

Full Mattress Size

Wider than a twin, but smaller than a queen, the full size Leesa Mattress is perfect for a single adult to sleep soundly. Also referred to as a "double," the full-size mattress is optimal for a single adult who wants more space than a twin or for a couple who doesn't mind snuggling through the night.

Queen Mattress

Queen Mattress Size

The most popular mattress size, the queen-sized Leesa mattress is six inches longer and six inches wider than a full size mattress, making it a naturally comfortable choice for most couples. Adding a Queen Leesa Mattress to your bedroom suite will bring you night after night of cooling, body contouring and core support.

King Mattress

King Mattress Size

Buying a king size Leesa mattress will give you an added 16 inches of width over a queen mattress (the length is the same), which means you’ll have plenty of space to read, roam, roll, play, dream and sprawl over the course of a night. You’ll instantly fall in love with the three-layered design, the soft coziness of our single-piece cover.

Cal. King Mattress

Cal King Mattress Size

Long on comfort, the California King mattress isn't quite as wide as a regular king mattress, but it offers an extra four inches of length over the queen and king mattresses. So if you or your sleep partner is very tall, you may find benefit in choosing the Leesa Cal King size.
