Beautyrest Black Hybrid XCS Series Three Plush Mattress

Hybrid Support, Plush Comfort

Beautyrest Black® Hybrid XCS Series Three builds on the Triple-Stranded Pocketed Coil® foundation with FORM™ HD Material, Dynamic Response® Memory Foam, and Micro Diamond™ Memory Foam for individualized support with a cool-to-the-touch surface. In the Plush feel, those comfort layers cradle the body deeply, letting the coil system underneath keep everything supported.

BlackICE® Max Cooling Technology and the cool-to-the-touch Sleep Climate™ Surface keep that plush comfort cool through the night.

Built For

Since 1925

Pioneers of Pocketed Coil® Technology

Beautyrest invented the pocketed coil — individually wrapped coils that move independently for targeted support and true motion isolation, keeping movement on one side of the bed from disturbing the other.

Advanced Coil System

Triple-Stranded Pocketed Coil® Technology

Triple-Stranded Pocketed Coil® Technology delivers individualized, head-to-toe support and true motion separation, conforming to your unique shape underneath the plush comfort layers.

Sleep Position

Side Sleepers

The Plush feel cradles pressure points at the shoulders and hips with a soft, contouring surface, making it well suited to side sleepers who want deep pressure relief.
