Twin Mattresses

This is the most common size found in children's rooms, and is used on daybeds, trundle units and hideaways. The width of a twin mattress (39") is the minimal amount of space needed for a single person to lie comfortably each night. Two twin sized mattresses side by side equal the dimensions of a king sized mattress, which is why they are used for daybeds.

Pros: Has the proper width for one child or adult to sleep comfortably with enough sleeping surface. Easily fits into smaller rooms without taking up too much space. You can create a king sized mattress by putting two twin sized mattresses together.

Cons: Twin mattresses are too small for couples. They also may not be long enough for taller individuals to sleep comfortably.
