The K Class Firm Pillow Top scores a 4.5 on our Comfort Scale, which is on the firmer side of medium. In my opinion, this comfort level is almost perfect for back sleepers who like a firmer level of comfort. It creates the initial softness required to contour to your lower back, but it also offers really substantial and solid underlying support.

The T3 Pocketed Coil System is made using three steel strands that are braided into one solid coil that absorbs energy, dampens motion transfer, and provides outstanding durability, support, and undisturbed sleep.

BlackICE 4.0 and RightTemp Memory Foam are both found in this mattress to ensure you can experience an exceptionally cool sleep environment. BlackICE 4.0 features four components to guarantee you have a cooler sleep surface, while RightTemp Memory Foam pulls heat away from the surface and dissipates it throughout the night.

CertiPUR-US certified comfort materials are independently and thoroughly tested to meet or exceed the highest quality standards in bedding today.
