A quality innerspring mattress should last between 7 and 10 years before it needs to be replaced. Memory foam and latex models should last between 10 and 20 years depending on the manufacturer and the quality of the bedding. This is an approximation, as many factors affect the lifespan of a mattress. Keep in mind that just because a mattress is in good condition, that does not mean you are still getting the best comfort out of it.

Mattresses should be placed atop a firm base to prevent sagging. A new mattress should be rotated once a month for the first six months and once every 2-3 months after that. Double sided, or two sided, mattress should be alternately flipped & rotated. It is suggested that you rotate (spin) your boxsprings/foundation twice a year. Folding and bending of the mattress should be avoided if possible, as should heavy wear in one spot and excessive weight on the handles. Mattresses should not be soaked, lest mildew develop inside the upholstery; instead, they can be cleaned with a vacuum or with mild surface cleanser and a slightly damp cloth. Mattress Protectors help prevent stains and soiling of the ticking.

Once a mattress no longer feels supportive and instead seems to contribute to body pain or stiffness, it should be replaced. Some symptoms of a broken or worn out mattress include springs which can be felt poking through the upholstery layer, visible permanent sagging or deformity, lumpiness, and excessive squeaking.

Queen size mattress sets should be supported by a 5 or 6 leg frame. A queen size mattress is 60" wide and requires more support than smaller sizes. If using a headboard/footboard style bed make sure you are using at least 5 wood slats with 3 positioned primarily in the center third of the bed.
