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.

Coil Technology

World Class® Level Three steps up to 1000 Density Pocketed Coil® Technology for premier individualized support and motion separation, so movement stays contained and support responds to your body head-to-toe.

What's Inside

  1. 1 SurfaceTouch™ Gel Memory Foam — gel memory foam quilted into the surface for instant, cool-touch pressure relief.
  2. 2 Beautyrest® ActiveResponse™ MAX Memory Foam — contouring memory foam for upgraded, responsive pressure relief.
  3. 3 World Class Relief™ High Density Foam — a temperature-responsive foam layer that reacts to body heat for remarkable pressure relief.
  4. 4 1000 Density Pocketed Coil® Technology — individually wrapped coils at 1000 density for premier individualized support and motion separation.
  5. 5 InfiniCool® MAX Technology — a cool-to-the-touch surface plus natural lux fibers that help move excess heat away from the body.
Feel & Support

Built for an Extra Firm Feel

This is the firmest option in the World Class™ Level Three line — the coil layer does the majority of the supporting work, with thin comfort layers on top for a stable, minimal-sink surface.

Why it matters:

  • Maximum support — minimal sink for back and stomach sleepers
  • Firmest option in Level Three — less contouring than Medium-Firm, Medium, or Plush
  • Stable surface — coil support stays close to the surface
Cooling

Cool-to-the-Touch with InfiniCool® MAX Technology

InfiniCool® MAX Technology gives the World Class™ Level Three Extra Firm a cool-to-the-touch surface, and natural lux fibers add breathability for heat dissipation through the night.

Why it matters:

  • Cool-to-the-touch surface — comfortable from the moment you lie down
  • Breathable fibers — help move excess heat away from the sleep surface
Made to Last

Certified Foams, Backed for the Long Haul
