Full Size Mattresses
Full Mattress Dimensions are 54" x 75"
The twin mattress is the most common size found in children's rooms, and has the perfect dimensions to be 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.
Pros: The dimensions of a twin size mattress allows one child or adult to sleep comfortably with enough sleeping surface. Twin mattresses easily fit into smaller rooms without taking up too much space. You can also 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.
