FAQs
Why would I choose a Twin XL mattress?
You would choose a Twin XL mattress if you are a single adult living in a very small space like a studio apartment, a college student staying in a dorm, have an extra tall child upgrading to their first big bed or want/have a split king set up.
Is a Twin XL bed the same length as a full sized bed?
No. A Twin XL is actually approximately 5 inches longer than a Full size. But a Full is 15 inches wider than a Twin & Twin XL.
What is the difference between a Twin and a Twin XL mattress?
The only real difference between a Twin and a Twin XL is about 5 inches in length. Twin XL is longer than a Twin.
Will a twin XL mattress fit a twin bedframe?
No. Despite the difference in length is only about five inches between a Twin and Twin XL, the Twin XL mattress will not fit into a standard sized twin bed frame because it will be too long.
