Do I need a box spring with this mattress?

A box spring is optional but the support must be firm and flat. This 13-inch innerspring works on a platform bed, a slatted frame with gaps under 3 inches, or a traditional box spring on a frame. What it cannot use is an adjustable base. Solid, even support keeps the connected coil core from flexing in spots, which protects both the feel and the 10-year warranty.
