54″ × 75″ · A step up from a Twin for solo sleepers and smaller rooms
Full Mattresses on Sale
A Full, sometimes called a Double, is 54 inches wide and 75 inches long. It gives a single adult noticeably more room than a Twin and fits in smaller bedrooms and guest rooms where a Queen would feel oversized.
Full-size luxury mattresses are less common than Queens and Kings, so inventory in this size changes quickly. The listings below are authentic showroom and closeout models, and if nothing matches today you can leave your number and we will text you when one arrives.

Is a Full big enough for two adults?
A Full gives each person about 27 inches of width, less than a crib mattress, so most couples find it tight over the long term. It works best for one sleeper, a teen, or occasional guests.
It is also 5 inches shorter than a Queen, so people over about 6 feet may find their feet reach the end. A Twin XL or Queen is usually a better fit for taller sleepers.
Where a Full makes sense
Guest rooms, studio apartments, a first adult bed, and kids' rooms are the typical uses. If you may add a partner later, buying a Queen now can save a second purchase.
Check that your frame is a Full; the dimensions are standard, so any Full frame, sheet set and protector will fit.
