Young Brunette Girl On The Floor Posing On The Mattresses

A mattress may absorb up to 3 gallons of sweat and other fluids in its lifetime, causing wear and stains. 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 and larger size mattress sets should be supported by a 5- or 6-leg frame. A queen size mattress is 60 inches wide and requires more support than smaller sizes. If using a headboard/footboard style bed, one should use at least five wood slats with three positioned primarily in the center third of the bed.
