Full Mattress

Sometimes called a double mattress, a full-size mattress offers much more sleeping area width than the twin size mattress. Its dimensions are 75 inches in length by 54 inches in width. If you were to divide the full mattress in half and try to share it with someone else, each person would get about 27 inches of sleeping width, which is close to the width of crib mattresses. Therefore, with its 16 extra inches of width compared to a twin mattress, the full mattress is best for one active sleeper.
