Twin XL size mattress

A twin XL size mattress is 5 inches longer than a twin, making it perfect for growing children or adults with a small space. A twin XL is the standard mattress size for most colleges. Plus, two twin XL mattresses together make a king. This setup is ideal for a split adjustable base , so you and your partner can both customize your ideal sleeping position.

Full size mattress

A full-size mattress sometimes called a "double," is wider than a twin but smaller than a queen-size mattress. A full is great for a child to grow into or for a single sleeper who wants more space than a twin offers.

Queen size mattress

A queen-size mattress is the most popular mattress size, giving you an extra 6 inches of width over a full-size mattress. A queen is a great choice for single sleepers (and your furry friend!) and couples who may not have enough space for a king-size mattress.
