Beautyrest Black Hybrid Series Three XCS Firm Mattress

Firm support. Precise alignment. Cool, uninterrupted rest.

If you prefer a firmer, more supportive feel, the Beautyrest Black® Series Three XCS Firm Hybrid Mattress is designed to keep your body aligned while still delivering comfortable contouring. It adapts to your shape without excessive sink, so you feel supported—not stuck—throughout the night.

Advanced cooling features help regulate temperature, while motion-reducing support minimizes disturbances from a partner. The result is a firm, stable sleep surface that still provides pressure relief where your body needs it most.
