2019’s Top Value Extra Firm Mattress

by Jed Harrington

If you like an extra firm comfort level, the Beautyrest BRS900-C King Size Mattress is our number one choice for 2019. Cooling technology, a solid support system, quality comfort materials-- this mattress has it all, and for a reasonable price.

One of the Firmest Choices Available

Scoring a 1 on our Comfort Scale, the BRS900-C is among the firmest models available from our site. If you like a comfort level that feels firm and dense, this is the best choice.

Firm Support With Contouring

The Pocketed Coil system used to make the BRS900-C is extra thick to contribute to the overall extra firm comfort level. This system closely contours to the body while ensuring solid support. It's adjustable base compatible and helps keep transfer of motion at a minimum for undisrupted nights of sleep.

Offers Cooler Nights of Sleep

DualCool Plus Technology includes an antimicrobial performance layer that ensures your mattress is fresh and cool, while also aiding in dissipating heat for a cooler sleeping temperature.

Edge to Edge Comfort

You can rest comfortably anywhere on the surface without feeling as if you're going to roll off the side or feel forced back toward the center. The foam-encased edge support is a game-changing feature because it adds up to 10% more usable sleeping space compared to a mattress with no edge support.

My Suggestion For Value and Extra Firm Comfort

This mattress comes with everything you need and more to enjoy extra firm comfort-- all without hurting your wallet. It’s certainly my number one choice for best value in the extra firm category. If you’re on the lookout for an exceptionally firm mattress that won’t break the bank, I recommend that you go with this one.


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.
