## Overview

The Sealy® StableSupport Foundation has been engineered to provide the ideal surface for Sealy® mattresses. The solid, flat construction ensures that your bed will maintain its comfort and support for years to come, while a high-quality navy fabric complements the overall aesthetics of every Sealy® mattress. The Sealy® StableSupport Foundation also offers two distinct height options. A 9” height matches a traditional box spring, and a lower 5” profile creates a modern look that can easily fit through narrow stairways.
