The Saatva 11.5 Classic mattress is a luxurious hybrid mattress that combines the contouring support of individually wrapped coils with the pressure-relieving comfort of memory foam. Its patented lumbar zone technology provides extra support for your lower back, while the border-edge foam encasement prevents sagging and enhances edge support. The mattress is designed to be used with a Saatva with a Grey Square-stitched Platform Bed Frame. This frame is made of solid hardwood with a sleek, modern design. This frame is designed to provide superior stability and support, while its 11.5″ profile allows you to enjoy a more luxurious look and feel. The frame is also equipped with adjustable legs so you can customize the height of your mattress for your comfort.
