Delivering targeted support, the Starley mattress indulges you in restorative comfort worthy of the elite Posturepedic Plus collection. This plush pillowtop model features SealyCool™ gel memory foam sewn into the quilt, strengthening the core and keeping your mattress cool. An extra layer in the center adds conformance and durability. To reduce motion transfer, the specially-engineered Response Pro™ HD encased coil system consists of densely packed, durable coils that adjust individually. A soft cover with Chill™ technology feels cool to the touch while protecting against dust mites, dander and other bacteria using AllergenProtect™. Reinforcing pressure relief, ISO Motion Advanced gel memory foam contours to your body as it dissipates excess heat. The mattress edge is surrounded by DuraFlex™ coils, creating a solid surface for seating as well as more sleep space. In addition, its ventilated design offers refreshing airflow. 10 Year Limited Warranty
