Beautyrest World Class Hybrid Level Three Medium Mattress

Hybrid Support, Built Medium

The World Class™ Hybrid Level Three Medium is Beautyrest's smooth-surface alternative to the classic quilted World Class® line — 1000 Density Pocketed Coil® Technology working together with high-density foam comfort layers instead of a quilted top. The medium feel balances support and cushioning, so it works well across sleep positions.

It's built with 1000 Density Pocketed Coil® Technology, World Class Relief™ High Density Foam, Beautyrest® ActiveResponse™ MAX High Density Memory Foam, and a cool-to-the-touch InfiniCool® Technology surface.

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

1000 Density Pocketed Coil® Support

World Class® Hybrid Level Three steps up to 1000 Density Pocketed Coil® Technology for premier individualized support and motion separation, in a hybrid build with increased foam thickness overall.

Sleep Position

Balanced Support for All Sleepers

The Medium feel balances cushioning and support on a smooth hybrid surface, so it suits back, stomach, and side sleepers alike.

Construction

What's Inside

  1. 1 Beautyrest® ActiveResponse™ MAX High Density Memory Foam — contouring, high-density memory foam for instant, body-conforming pressure relief.

Feel & Support

Built for a Medium Feel

This is the balanced option in the World Class™ Hybrid Level Three line — enough cushioning to relieve pressure points, enough coil support to keep the spine aligned, for sleepers who don't want to commit to a firm or plush extreme.

Why it matters:

  • Balanced feel — cushioning and support in equal measure
  • Versatile — works well for back, stomach, and side sleepers
  • Hybrid construction — smooth foam surface over a responsive coil core
Cooling

Cool-to-the-Touch with InfiniCool® Technology

InfiniCool® Technology gives the World Class™ Hybrid Level Three Medium a cool-to-the-touch surface designed to help move excess heat away from the body, so the mattress stays comfortable through the night.

Why it matters:

  • Cool-to-the-touch surface — comfortable from the moment you lie down
  • Heat dissipation — helps move excess body heat away from the sleep surface
Made to Last

Certified Foams, Backed for the Long Haul

CertiPUR-US® Certified & 10-Year Limited Warranty: Every foam layer in the World Class™ Hybrid Level Three Medium is CertiPUR-US® certified — made without formaldehyde, flame retardants, prohibited phthalates, or heavy metals, and tested to meet low-VOC standards for indoor air quality — and the mattress is backed by Beautyrest's 10-Year Limited Warranty.
