The Sealy Response Performance Prospect Lake is an 11.5-inch cushion firm innerspring mattress that delivers superior support and comfort for all-night sleep. Part of the Sealy Posturepedic collection, this mattress features exclusive Posturepedic Technology with an extra layer of premium materials reinforcing the center of the bed, providing targeted support where you need it most—under the heaviest part of your body. The mattress is constructed with expertly engineered PrecisionFit coils that flex to your body's individual needs, offering immediate support with stronger deep-down support throughout the night. These exclusive coils are expertly arranged to provide all-night support and help maintain natural body alignment.

The comfort system includes SealyComfort Gel Foam that disperses weight across the mattress for added pressure relief, providing responsive cushioning and full-body comfort. The SupremeLoft Knit Cover features MoistureProtect technology that wicks away moisture from your body to keep you cool, plus Surface-Guard Technology protects the mattress from common allergens to help the cover stay fresh. The DuraFlex Edge System reinforces the mattress edge and creates a solid seating surface that's built to last, maximizing the usable sleep surface.
