My Take on the Beautyrest BRS900 Medium Firm

by Jed Harrington

The Beautyrest BRS900 Medium Firm Full XL Size Mattress makes a smart choice if you're looking to keep your cost down but still get a great mid-tier mattress with a firm comfort level that’s not incredibly hard. This mattress features a solid coil system, thoroughly tested comfort materials, and a great edge support-- everything necessary to get quality sleep without breaking the bank.

Scores a Rating of 4 on Our Comfort Scale

Getting a Comfort Scale score of 4 out of 10 (10 being the softest), the BRS900 Medium Firm offers exactly the kind of comfort most people picture when they say they like a firm mattress. Its initial padding keeps you from feeling as if you’re sleeping on a carpeted floor, and it offers adequate body contouring while supplying solid lower back support.

Solid Support From an Excellent Coil System

One of the best coil systems on the market, the Beautyrest Pocketed Coil System contours to the unique shape of your body while guaranteeing there’s plenty of solid lower back support. Built from high carbon steel, this coil system is made to last, and it’s fully compatible with all modern adjustable bases. The simple but effective design helps minimize transfer of motion for sound nights of sleep.

Tend to Sleep Warm? This Mattress Can Help.

Dual Cool Technology creates a cooling surface that will ensure you can sleep comfortably cool throughout the night.

Edge Support Ensures Consistent Comfort

It’s okay to sleep close to the edges without feeling like you're going to roll off the side or feel forced back toward the center. The foam-encased edge support is a highly beneficial feature since it creates up to 10% more usable sleep surface compared with mattresses that don’t have an edge support.

Is the BRS900 Medium Firm the Right Choice for Your Preferences?

Are there better options available from the Silver collection? Yes. But for the money, the Beautyrest BRS900 Medium Firm is able to deliver a level of comfort and support that makes it a fantastic choice in the mid-price mattress category. This mattress is dependably made and comes backed by a generous 10-year warranty to ensure your satisfaction.
