The Sealy Posturepedic "West Salem" is a California King cushion firm innerspring mattress from the Sealy Response Premium collection. It features Sealy's exclusive Posturepedic Technology, which precisely engineers the mattress into specific zones to deliver reinforced support where you need it most, targeting the heaviest part of your body while providing exceptional full-body comfort.

The mattress includes a SupremeLoft Knit Cover with Moisture-Wicking and AllergenDefence Technology, helping to regulate temperature and protect against common allergens. The center third of the mattress incorporates SealyConform Gel Memory Foam for targeted pressure relief and cooling comfort. A DuraFlex Edge System surrounds the mattress with high-density, flexible coils for better edge support, a more usable sleeping surface, and improved durability. Additional comfort layers include SealySupport Foam and a FlameGuard Fiber quilt layer. The mattress is backed by a 10-year limited warranty and is eligible for Costco's White Glove Delivery, which includes in-home setup and removal of packing materials.
