King Beautyrest Black L-Class Extra Firm Mattress

The Beautyrest Black BRB L Class Extra Firm offers one of the firmest feels of any innerspring mattress. We rate this mattress a 10 on our 1 to 10 comfort scale with 10 being firmest. The New BlackICE 4.0 now uses four cooling components to provide you with an even cooler more comfortable sleep. The combination of Firm Comfort Foam and Extra Firm Comfort Foam allows for a firm yet contouring still providing adequte pressure relief. This mattress uses the T3 Pocketed Coil Technology, a triple triple braided high carbon steel, to provide superior contouring and long term durability.
