My Thoughts Concerning the Beautyrest BRX3000 IM Medium Firm

by Jed Harrington

The Beautyrest Hybrid BRX3000 IM Medium Firm California King Size Mattress is crafted using some of the top materials in the Beautyrest lineup, and it comes with all you need to enjoy comfortably cool nights of sleep. If you’re on the lookout for a mattress that feels firm, but not overly so, this is a fantastic choice.

Contour Fit Design Ensures Comfort That’s Consistent

Right at the top, the BRX has one of my favorite features in the bedding industry: a smooth-top, stretch-knit cover. This cover puts almost no barrier between your body and the comfort layers, and this allows for a very consistent level of comfort.

Specially Engineered For Cooler Nights of Rest

The BRX is all about ensuring you can sleep comfortably cool throughout the night. InfiniCool MAX creates a cool to the touch sleeping surface as well as an underlying layer of further temperature management. A layer of RightTemp Memory Foam aids in separating heat from the mattress and dissipates it over time as you rest.

Enhanced Support At the Top

BackCare 3X consists of thousands of micro coils that can adapt to the unique curves of your body to enhance conformability, comfort, and support.

Independently Tested and Certified Comfort

CertiPUR-US certified comfort materials are independently and thoroughly tested to meet or exceed the highest quality standards in the bedding industry, so you can be fully confident that this is a high quality mattress.

Is This Model the Perfect Match For You?

If you would like a firm comfort level and want to start enjoying the benefits of the Beautyrest Hybrid collection, the Beautyrest Hybrid BRX3000 California King Size Mattress makes an excellent choice.


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
