The Beautyrest World Class™ Hybrid Level 4 Plush 13.5" Mattress pairs 1000 Density Pocketed Coil® Technology with 2X the World Class Relief™ High Density Foam and thicker ActiveResponse™ MAX High Density Memory Foam layers for a smooth, plush hybrid feel built for side sleepers. Cool-to-the-touch InfiniCool® Technology and Beautyrest’s 10-Year Limited Warranty back this 13.5" mattress.

Beautyrest World Class Hybrid Level Four Plush Mattress

Smooth Hybrid Comfort, Built Plush

The World Class™ Hybrid Level 4 Plush pairs 1000 Density Pocketed Coil® Technology with a smooth, contouring hybrid surface — a smooth-surface alternative to the classic quilted World Class® innerspring line. Level Four doubles the World Class Relief™ High Density Foam versus World Class® Hybrid Level Three, plus thicker layers of ActiveResponse™ MAX High Density Memory Foam for upgraded contouring comfort.

The Plush feel is built for side sleepers who want extra cushioning at the shoulders and hips, while cool-to-the-touch InfiniCool® Technology helps keep the surface from trapping heat.

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

Side Sleepers

The Plush feel cushions the shoulders and hips, easing pressure points for side sleepers while the coil layer keeps the surface supportive underneath.

Cool-to-the-Touch

Surface-Level Cooling

InfiniCool® Technology keeps the sleep surface cool to the touch, helping move excess heat away from the body throughout the night.

Construction

What's Inside

  1. 1 World Class Relief™ High Density Foam — doubled in Level Four versus World Class® Hybrid Level Three, this layer responsively reacts to body temperature for remarkable pressure relief.
  2. 2 Beautyrest® ActiveResponse™ MAX High Density Memory Foam — thicker layers in Level Four for upgraded contouring comfort and a responsive, body-conforming feel.
  3. 3 1000 Density Pocketed Coil® Technology — premier individualized support and motion separation for an undisturbed rest.
  4. 4 InfiniCool® Technology — a cool-to-the-touch sleep surface engineered to move excess heat away from the body.
  5. 5 Hybrid Smooth Surface — smooth, contouring construction distinct from World Class®’s classic quilted innerspring build.
Feel & Support

Built for a Plush Feel

This is the Plush option in the World Class™ Hybrid Level Four line: thicker ActiveResponse™ MAX High Density Memory Foam layers cushion the shoulders and hips for a soft, contouring surface, while the 1000 Density Pocketed Coil® layer keeps the mattress supportive underneath.

Why it matters:

  • Deep, cushioning sink — extra ActiveResponse™ MAX High Density Memory Foam for pressure relief at the shoulders and hips
  • Body-conforming comfort — World Class Relief™ High Density Foam responsively reacts to body temperature
  • Supportive coil foundation — 1000 Density Pocketed Coil® Technology keeps the plush surface from bottoming out
Profile Height

A Consistent 13.5" Profile

The World Class™ Hybrid Level 4 Plush 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
Made to Last

Certified Foams, Backed for the Long Haul
