Our flexible slat foundation is designed to do more than merely support your mattress—it is designed to support YOU. The curved slats in our foundation provide both suspension and contour for greater comfort and pressure reduction. And the slat system is fully adjustable and dual-sided to meet the needs of individual sleepers. Based on a design widely used in Europe, we have adapted the system to meet the needs of American consumers. Our flexible slat foundation replaces your box spring and fits in any standard-sized bed frame. Paired with one of our flexible, supportive mattresses, it is an integral part of our system.
