The Best Value Extra Firm Mattress of the Year

by Jed Harrington

If you like an extra firm comfort level, the Beautyrest BRS900-C Twin XL Size Mattress is our top choice for 2019. Quality comfort materials, cooling technology, a solid support system-- this mattress has it all, and for a reasonable price.

One of the Firmest Models Available

With a Comfort Scale rating of 1, the BRS900-C is one of the firmest models available on our site. If you want a comfort level that feels firm and dense, this is the way to go.

Incredibly Firm Support

The Pocketed Coil system utilized in the BRS900-C is extra thick and contributes to the extra firm comfort level. This system contours well to the curves of the body while offering solid support. It's adjustable base friendly and helps isolate motion transfer for undisrupted nights of sleep.

Built For Cooler Sleep

DualCool Plus Technology has an antimicrobial performance layer that works to keep your mattress fresh and cool, while also helping to dissipate heat for a cooler sleeping temperature.

Consistent Comfort From Edge to Edge

Sleep anywhere on the mattress 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 great feature, which adds up to 10% more usable sleep surface compared to mattresses with no edge support.

The Top Choice For Value and Extra Firm Comfort

This mattress comes complete with everything you need to enjoy extra firm comfort, without breaking the bank. It’s my top pick for best value in the extra firm category. If you would like an exceptionally firm mattress that doesn't break the bank, 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.

Box Spring - Foundation (optional)

  • Regular Box Spring Height: 9
  • Low Profile Height: 5
