The K Class Firm Pillow Top scores a rating of 4.5 on our Comfort Scale, which is on the firmer side of medium. In my opinion, this level of comfort is almost perfect for back sleepers who like a firmer feel. It offers the initial softness required to contour to your lower back, but it also has 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, minimizes motion transfer, and ensures outstanding durability, support, and undisturbed sleep.

BlackICE 4.0 and RightTemp Memory Foam are both used in this mattress to ensure you can experience a pleasantly cool sleep environment. BlackICE 4.0 features four components that give you 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 extensively tested to meet or exceed the highest quality standards in the bedding industry today.
