Affordably Priced Extra Firm Comfort

by Jed Harrington

The Beautyrest BR800 Firm King Size Mattress supplies an extra firm comfort level at an affordable price point. This is one of the best ways to keep your cost down, but still enjoy an extra firm comfort level.

Targeted Support With an Extra Firm Feel

The comfort materials are really simple and are made using high quality poly foams that are CertiPUR-US Certified to either meet or exceed the highest quality standards. Scoring a Comfort Scale rating of 1.5, the BR800 Firm feels very firm, similar to sleeping on a carpeted floor. If that's the kind of comfort level you’re looking for, this is a great way to go. The Gel Memory Foam Lumbar support delivers additional lower back support and helps ease pressure points.

Excellent Support At a Low Price

The 800 Series Pocketed Coil System offers customized support as well as a high degree of conformability. This system is made using high carbon steel and is dependably constructed to easily last the next 10 years.

Sleep Comfortably Cool

The DualCool Technology layer built into the quilt has recently been added to this line, and it wicks away moisture to ensure cooler nights of sleep.

Fully Sleep System Friendly

The Beautyrest BR800 Firm is conveniently compatible with all modern adjustable bases and power foundations. You can easily switch to a sleep system with the knowledge that your mattress is going to perform well over time.

An Amazing Choice for Extra Firm Comfort

If you’re looking for an extra firm comfort level and don't want or need many of the extra features used in a higher end model, the BR800 Firm may be the perfect choice. This mattress is dependably built to ensure it will supply extra firm comfort and support well into the next decade.

Comfort - Padding Layers This provides a cushioning layer between you and the support system in the bed. Different kinds of padding will provide different levels of comfort.
