The Sealy Response 11.5" Performance Prospect Lake Twin Mattress features cushion firm support that delivers comfort and stability, making it ideal for day beds, bunk beds, or anywhere a twin size mattress is needed. This innerspring mattress combines traditional support with modern comfort technologies.

The mattress features a SupremeLoft Knit Cover with high loft, soft knit fabric made with durable spun yarns for a plush, comfortable feel. The cover includes MoistureProtect technology to draw moisture away from your body for cooling comfort, and AllergenProtect to guard against common allergens like dust mites and dander. Inside, SealyCushion Ultra Soft Foam layers provide pressure relief and contouring comfort.

The DuraFlex Edge System is engineered around all four edges of the mattress, providing firm support and creating a consistent sleep surface from edge to edge. This high-density, flexible coil border maximizes the usable sleep surface and prevents sagging along the perimeter. The innerspring coil support system delivers responsive support that adapts to your body's movements throughout the night.

Mattress dimensions are 38" W x 74" L x 11.5" H. The cushion firm feel rates approximately 7-8 on a firmness scale, making it particularly well-suited for back and stomach sleepers who need proper spinal alignment. Box spring is not included and must be purchased separately.
