Shop Full Firm Mattresses

Overview

A firm full mattress is a classic choice for a bed. At 54" by 74", a firm full bed is a versatile choice for growing children or solo adult sleepers or even an pair of sleepers, if necessary but it's not too large for smaller rooms. A full firm mattress also benefits from the classic firm feel, which provides the right amount of support and long-lasting comfort.
