The same length as full size mattresses, they are ideal for tight spaces.. . Most of the covers Cotton Cloud Futons sells are designed to fit a 6" thick mattress.
It's a narrow bed that's easy to make and can fit almost anywhere. Width per person: 39 inch. Twin XL, 39" x 80". Generally used in college dorm rooms, 5" longer .
