The One.

Meet The One - the only mattress we make, because it's the only one you need. Twelve inches of cooling comfort built around 800 edge-to-edge coils, with a phase-change cover that pulls heat away the moment you lie down and a breathable open-cell comfort layer that keeps it that way all night. The reinforced perimeter gives you up to 25% more usable sleeping surface, so a queen finally sleeps like one — right up to the edge. No fiberglass, no chemical flame retardants, no showroom markup. Just a medium-firm feel that works for side, back, stomach, and couples, built in the USA with CertiPUR-US® certified foams and backed by a lifetime warranty. Not too firm. Not too soft. Just right.
