Beautyrest Black Series Three 14.25" Extra Firm Mattress

The Series Three Extra Firm is the rarest firmness in the lineup and the easiest one to recommend if you know you need it. 14.25" of build, a firm-plus surface with almost no sink, and steady spinal alignment all night. If you've been told to sleep on something extra firm — or if you've been waking up with back pain on anything softer — this is the mattress.

The support system is advanced individually pocketed coils paired with pressure-relieving comfort foams. The coils respond independently under each part of your body, which targets support where you weigh more and keeps motion transfer low. Cooling cover technology pulls heat off the surface to keep things temperature-neutral.

Best for: Back and stomach sleepers who prefer a structured surface.

The honest part: Factory second — minor cosmetic imperfections, no manufacturer warranty. The mattress sleeps exactly like the full-price version.
