Sealy Posturepedic's Valley Road mattress includes a hybrid design with a firm, supportive feel. A stretch-knit cover with SealyChill and Surface-Guard technology combines cooling fibers with antimicrobial properties, feeling cool to the touch while protecting against dust mites, dander and other bacteria. Delivering pressure relief, ComfortSense memory foam naturally conforms to your body and distributes weight evenly. SealySupport gel foam provides a supportive foundation. To reduce motion transfer, the specially-engineered Response Pro encased coil system consists of densely packed, durable coils that adjust individually for personalized comfort. Enhancing flexibility, the mattress edge is surrounded by DuraFlex coils that create a solid surface for seating as well as more sleep space. 10 Year Non-Prorated Warranty
