We encourage you to buy a foundation when you buy your mattress; it provides the solid base your mattress requires to do its job properly. If you choose not to purchase our foundation, you must position the mattress on a completely flat, solid surface with adequate center support. Do not use the mattress with a conventional box spring. Please note that using the mattress without a Stearns & Foster®, Tempur-Pedic® or Sealy® foundation, or similar firm, solid-surface, non-spring base may void the warranty.
