Made With Luxury Materials

by Jed Harrington

The Beautyrest Black C Class Medium was designed with a great deal of attention to detail and with the goal of supplying one of the most impressive firm luxury mattresses available.

Firm Comfort, But Not Hard

The C Class Medium is built to deliver a firm overall feel, but it consists of enough padding to keep it from feeling hard. This design scores a 3 out of 10 on our Comfort Scale, with 10 being the softest. Layers of RightTemp Memory Foam and Beautyrest Gel Memory Foam work with one another to encourage deep REM sleep, ease pressure points that lead to tossing and turning, and dampen transfer of motion.

High Grade Support

The T3 coil system is built from high carbon steel and makes use of triple strand engineering to improve support and pressure relief. It offers exceptional support with less motion transfer for deep, undisturbed sleep.

Double the Cooling Effect

The C Class contains two big cooling features that cooperate with each other to help ensure a thermal neutral sleeping space. The BlackICE 4.0 system works together with the layer of RightTemp Memory Foam to separate heat from the surface and disperse it over time.

Dampens Transfer of Motion

Generous layers of premium memory foam react with the T3 coil system to reduce motion transfer when there’s movement, so you can spend more time resting.

Truly Impressive Luxury Comfort

This mattress has been carefully engineered to supply some of the best sleep that money can buy. From the coil system to the high end comfort materials, it's an amazing mattress that will keep you cool and comfortable throughout the night.
