Affordably Priced Extra Firm Comfort

by Jed Harrington

The Beautyrest BR800 Firm Full XL Size Mattress offers an extra firm comfort level for an affordable price point. It’s one of the best ways to keep your cost at a minimum, but still enjoy an extra firm feeling of comfort.

Extra Firm Comfort Level With Targeted Support

Comfort components in the BR800 Firm are quite simple and consist of high quality poly foams that are CertiPUR-US Certified to either meet or exceed the highest quality standards. Featuring a Comfort Scale score of 1.5, the BR800 Firm feels very firm, almost like sleeping on a carpeted floor. If that's what you're on the lookout for, this is a good way to go. The Gel Memory Foam Lumbar support supplies additional support to the lower back and helps reduce pressure points.

Excellent Support For a Low Cost

The 800 Series Pocketed Coil System delivers individualized support and a high degree of conformability. This system is incorporated by utilizing high carbon steel and is made to easily last the next 10 years.

Comfortably Cool Nights of Sleep

The DualCool Technology layer built into the quilt is new to this line, and it wicks away moisture to provide a cooler night of sleep.

Completely Sleep System Compatible

The Beautyrest BR800 Firm will function with all modern adjustable bases and power foundations. You can easily upgrade to a sleep system with the confidence that your mattress is going to continue to work well over time.

A Great Choice for Extra Firm Comfort

If you prefer an extra firm feel and don't want or need many of the extra features used in a higher end model, the BR800 Firm is an excellent choice. This mattress is dependably built to provide extra firm comfort and support well into the next decade.
