The Sealy Posturepedic StableSupport Foundation is a full-size (74" x 53") flat foundation engineered to provide the ideal surface for Sealy Posturepedic mattresses. Its rigid, flat construction distributes weight evenly and optimizes the comfort and longevity of your mattress investment.

Available in a high-profile 9" height that matches a traditional box spring or a low-profile 5" option for a more modern, lower-to-the-ground look that fits more easily through narrow stairways. The foundation is compatible with all mattress types including foam and innerspring, and fits most standard bed frames. Upholstered with high-quality textiles and corner guards to complement any bedroom décor.

The foundation is assembled in the USA and backed by a 10-year limited warranty. It pairs seamlessly with all Sealy Posturepedic mattress collections and is sold as a standalone foundation unit (mattress not included).
