Mattresses

The Original Mattress Factory offers a wide selection of hand-built full-size mattresses. Full-size mattresses are 53 inches x 75 inches (± 1 inch). Our full-size mattresses are available in 15 innerspring and three foam models, including two-sided and one-sided models and in comfort levels from soft to hard. We highly recommend you pair your new mattress with a real working box spring, as well as a heavy-duty frame that features a center rail for support.
