Designed to be stronger and more stable than a traditional box spring, the Leesa Mattress Foundation provides optimal support for foam and hybrid mattresses. Made with premium spruce slats spaced 4.5 inches apart, it ensures your mattress stays supported and comfortable night after night. The foundation is upholstered in a modern Tuxedo Grey fabric for a clean, polished look.
