Full and twin mattresses in Cornelius, NC

Twin, twin XL or full: the sizes

A twin is 38 inches wide and 75 inches long, the standard size for a child’s bed, a bunk bed or a daybed. A twin XL adds five inches of length (38 by 80 inches): the size of a dorm bed, the right call for a tall teenager, and the size that pairs up to form a split king on an adjustable base. A full, also called a double, is 54 inches wide and 75 inches long, a generous single bed and a workable size for a guest room where a queen will not fit.

Two adults can share a full, but with only 27 inches each it suits occasional use rather than every night. Couples are usually better served by a queen or a king.

Our mattress buying guide lists every standard size, from twin to California king, with its dimensions and who it typically suits.

Fitted like every other size

Smaller sizes get the same fitting as a king. Dream Mapping takes about five minutes on the sensor bed, costs nothing, and shows the Sleep Coach which comfort level and support the sleeper needs, which matters for a growing child as much as for an adult.

Mattress protectors are a sensible addition for kids’ and guest beds: they guard the mattress against spills, stains and allergens while keeping the feel of the mattress.
