Stearns & Foster Flat Foundation

Engineered to support your Stearns and Foster^® mattress with a perfectly solid, flat surface.

The perfect mattress isn't complete without the perfect foundation. Our flat foundations are designed to take the place of a traditional box spring and can be placed directly on your existing bed frame.

Constructed with the finest textiles, our Stearns & Foster^® foundation is designed to enhance the look and feel of your mattress.

Why you'll love it. Perfect Match

Our solid surface foundation is crafted to provide years of stationary support. Designed and upholstered to complement our mattresses and your bedroom décor.

Custom Comfort

Our foundations are available in a 9” height that matches a traditional box spring and a lower 5” profile for a more modern look that will easily fit through more narrow stairways.
