At the Top of the Beautyrest Mattress Line

by Jed Harrington

The Beautyrest Black K Class Firm Pillow Top includes everything you'd expect a top-tier model to have. It's brilliantly engineered to keep you comfortably cool while ensuring body-cradling pressure point relief and solid support to the lower back.

Firm Support Plus Comfort

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.

One of the Better Support Systems Available Today

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.

Sleep Cooler, Feel Refreshed

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.

Impressive Quality Guaranteed

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

Is This The Number One Option For Me?

If you're on the lookout for a Beautyrest mattress that has it all, the Beautyrest Black K Class Firm Pillow Top makes a wonderful choice. This mattress has an exceptional feel, high grade components, and a support system crafted using the finest construction in the Beautyrest line. That’s everything you need to start experiencing deep, restful nights of sleep.
