Stearns & Foster Box Springs and Foundations

A Stearns & Foster foundation provides the solid, flat support surface your S&F mattress needs to perform at its best. Using the manufacturer-recommended foundation ensures optimal comfort, proper support, and full warranty coverage for your investment. At LA Mattress Stores, we carry Stearns & Foster foundations in standard and low-profile heights at all five Los Angeles showrooms.

Foundation Options

  • Standard Height (9"): The traditional profile that pairs well with most bed frames and brings your mattress to a comfortable sleeping height.
  • Low Profile (5"): A reduced-height option ideal for thicker mattress models, platform-style beds, or sleepers who prefer a lower bed height.

Both options provide the rigid, non-flexing surface that Stearns & Foster mattresses require. The foundation distributes weight evenly, prevents mattress sagging, and extends the life of your mattress. Available in all standard sizes including split king configurations.

Our sleep experts can help you choose the right foundation height based on your bed frame, mattress thickness, and preferred sleeping height. Visit any of our five locations for personalized guidance.
