A plush European pillowtop, the Sealy Posturepedic Weldon mattress yields pressure relief and cooling comfort. A stretch-knit cover with MoistureProtect and Surface-Guard technology combines moisture-wicking material with antimicrobial properties, feeling fresh while protecting against dust mites, dander and other bacteria. SealyCool gel-infused memory foam provides cushioning and keeps your mattress refreshingly cool. With improved breathability, SealyCool air gel foam promotes airflow for a more comfortable sleep experience. To reduce motion transfer, the specially-engineered Response Pro encased coil system consists of densely packed, durable coils that adjust individually for personalized comfort. The center of the mattress is uniquely designed to target the heaviest part of your body for extra support. Enhancing flexibility, the mattress edge is surrounded by DuraFlex coils that create a solid surface for seating as well as more sleep space.
