Features

All K-Class Mattresses feature the T3 Pocketed Coil that is exclusive to the Beautyrest Black Collection. This triple stand coil provides the best support and durability that Beautyrest has to offer.

BlackICE 4.0 Technology provides superior cooling with a cool-to-touch sensation, heat dissipation just beneath the surface, silver additives to draw heat away from the body, and breathable SilkAIR fiber that prevents head buildup.

The K-Class also features a variety of high density memory foams that work together to give you the best pressure relief and conforming support that Beautyrest Black has to offer. With added RighTemp Memory Foam, this line sleeps 20% cooler than the L-Class line and has more advanced pressure point relief.

This line also features 2K Nano Coils (not included in L-Class or C-Class). These 2,000 micro coils provide superior pressure relief and conformability with individualized back support that matches any body type.
