The Beautyrest Black® Series One 13.5" Extra Firm Mattress pairs Triple-Stranded Pocketed Coil® Technology with Beautyrest® Gel Memory Foam in an extra firm feel built for back and stomach sleepers who want maximum support with minimal sink. Sleep Climate™ Technology keeps the surface cool to the touch, and a quilted surface, eight handles, velvet accents, and cashmere-blend fabrics deliver Series One's signature luxury build, backed by Beautyrest's 10-Year Limited Warranty.

Beautyrest Black Series One Extra Firm Mattress

Introductory Black® Luxury, Built Extra Firm

The Series One 13.5" Extra Firm is Beautyrest's entry point into the Black® collection, built with Triple-Stranded Pocketed Coil® Technology for head-to-toe individualized support and advanced motion separation. In the Extra Firm feel, the coil layer does more of the supporting work and the foam comfort layers stay thinner on top — less sink, more support, for sleepers who don't want a plush, contouring feel.

It's built with Beautyrest® Gel Memory Foam for contouring pressure relief and Sleep Climate™ Technology to help transfer heat away from the body, wrapped in a quilted mattress surface with eight handles, velvet accents, a quilted border, and cashmere-blend fabrics.

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, so movement on one side of the bed stays there.

Sleep Position

Back & Stomach Sleepers

The Extra Firm feel keeps sink to a minimum, so back and stomach sleepers stay supported and aligned on a firm, stable surface.

Temperature Management

Cool-to-the-Touch Comfort

Sleep Climate™ Technology helps transfer heat away from the body all night, so the surface stays cool to the touch instead of trapping heat.

Feel & Support

Built for an Extra Firm Feel

This is the firmest feel in the Series One lineup: minimal sink, with the coil layer doing most of the supporting work and Beautyrest® Gel Memory Foam kept thin on top.

Why it matters:

  • Minimal sink — supportive surface for back and stomach sleepers
  • Coil-forward feel — less body-contouring than a plush or medium feel
  • Consistent support — foam adds comfort without masking the coil support underneath
Profile Height

A Consistent 13.5" Profile

The Series One Extra Firm holds a 13.5" profile across every size in the collection.

Why it matters:

  • Consistent height — the same profile no matter which size you choose
  • Frame-friendly — fits standard bed frames, platform beds, and adjustable bases
