My Opinion On the Beautyrest BRX3000 IM Medium

by Jed Harrington

At this price point, it's hard to surpass or even come close to the Beautyrest BRX3000 IM Medium. This mattress is notably over-engineered because Beautyrest is trying to overtake the hybrid market at the moment. That means that this is the perfect time to search for a mattress that has a ton of features for the money, and you can get an incredible value in the luxury mattress category. You do, however, have to be okay with an extra firm comfort level because this mattress is quite dense.

Design That Closely Adheres to Your Curves

Right at the top, the BRX features one of my favorite materials on the market today: a smooth top, stretch-knit cover. This cover puts almost zero barrier between your body and the comfort layers to ensure that comfort is exceptionally consistent.

Ensures You Can Sleep Comfortably Cool

The BRX is brilliantly designed to help you experience comfortably cool nights of sleep. InfiniCool MAX supplies a cool to the touch sleep surface plus an underlying layer of expertly engineered temperature management. A layer of RightTemp Memory Foam pulls heat away from the surface and gradually disperses it as you sleep throughout the night.

Abundant Support At the Surface

BackCare 3X contains thousands of micro coils that change to fit your individual, unique shape to improve comfort, conformability, and support.

The Sole Model That Uses Latex

I've been a big supporter of incorporating latex into mattresses for a long time, and for good reason. Latex is one of the most advantageous and most underutilized materials in the bedding industry. It offers quality pressure relief, pushes back against the body for enhanced support, is naturally anti-microbial and anti-dustmite, and is amazingly durable. Having a layer of Comfort Response Latex in this mattress means you get to experience each of these quality benefits.

Is the BRX3000 IM Medium the Best Option For My Situation?

This year, Beautyrest pulled out all the stops and came out with an impressive high end hybrid mattress to compete well in this category. I strongly recommend this mattress if you're searching for not only one of the best hybrid models on the market, but also one that presents an unusually amazing value. If you are after an extra firm feel, this model will make a perfect choice.
