Description

Elevated support. Instant contouring. Advanced cooling comfort.

The Beautyrest Black® Series Four XCS Firm Hybrid Mattress builds on the support of Series Three by adding a more responsive, instantly contouring feel. It delivers firm support while adapting more quickly to your body, creating a more refined balance of pressure relief and stability.

An added layer of responsive support enhances how the mattress conforms to your shape, while advanced cooling and motion separation help you stay comfortable and undisturbed. It’s a firmer feel—but with a more adaptive, elevated comfort experience.

Best for back and stomach sleepers who want firm support with enhanced contouring and responsiveness.
