Quality Mid-Range Mattress

by Jed Harrington

The Beautyrest BRS 900 Medium Full XL Size Mattress blends certified, quality comfort materials with a highly rated coil system, resulting in a great all-around mattress with a comfort level that’s firm without being hard.

Firm But Comfortable Option

With a Comfort Scale score of 3 out of 10 (10 being the softest), this model feels comparable to a carpeted floor with thick padding. If you typically sleep on your back and want something firm but not hard, this should be a good choice for you.

Highly Effective Pocketed Coil System

The individually pocketed coil system provides solid support, good pressure relief, and exceptional body contouring. It's also good at dampening motion transfer, so you can continue sleeping undisturbed if movement occurs.

Technology That Helps You Sleep Cooler

The DualCool Technology incorporated in the quilt includes an antimicrobial performance layer that helps ensure your mattress is fresh and cool, while also wicking away moisture for a more thermal neutral sleeping space.

Great Attention to Lower Back Support

Gel Memory Foam Lumbar Support supplies reinforced support and durability to the lower back, improving support to where you need it the most.

Is This the Right Choice For You?

If you're searching for a budget friendly mattress with a firm but not hard level of comfort, the Beautyrest BRS900 Medium makes a fine choice. This mattress comes complete with a 10-year warranty, is made in the US, and includes everything needed to enjoy quality comfort for years to come.


Comfort This describes how a mattress feels. The Comfort Scale rating is based on how the cushioning materials conform to the body's shape. The higher the number the softer the mattress.

Quilt - Top of Mattress This is the outside cover on the top of the mattress. It covers and protects the comfort and support layers inside.

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.

Correct Back Support System This is a general term used to describe how a mattress distributes and stabilizes body weight and maintains proper spinal alignment. Different materials provide different levels of support.
