Also, the warranty protects you against defects in workmanship and materials. Body impressions are considered normal and the length of the warranty doesn't mean that the mattress will last that long. Body weight is a factor in how long a mattress will last. The more body weight you have, the shorter the life of the mattress.

Should be a 10-year warranty like most Posturepedics, provided it's not a floor model or comfort exchanged model.
