The Softest High Quality Model Available

by David Higgins

The Beautyrest Black® K-Class Ultra Plush Pillow Top is ideal for anyone searching for the best soft mattress Beautyrest has available. It comes with the very best comfort materials, support system, and cooling solution in the Beautyrest lineup, and it is designed to provide maximum pressure relief.

Soft, Enveloping Comfort Level

With a Comfort Scale rating of 7, the Beautyrest Black® K-Class Ultimate Plush Pillow Top is among the softest mattresses in this collection. Whether you're a side sleeper who wants maximum pressure relief or a back sleeper who is searching for a mattress that envelops the body, this mattress will provide everything you're looking for.

High Quality Support System

The T3 Pocketed Coil System consists of three steel strands, all braided into one solid coil that absorbs energy, isolates motion transfer, and provides remarkable support, durability, and undisturbed sleep.

Multistage Cooling System Is Foolproof

BlackICE 4.0 which incorporates natural all night cooling and SurfaceTouch Gel Memory Foam and Air Feel Foam are all included to ensure you have an exceptionally cool sleeping space. BlackICE 4.0 is made up of four components to provide a cooler sleeping surface, while the SurfaceTouch Gel Memory Foam pulls heat away from the surface and distributes it throughout the night.

Amazing Quality Guaranteed

The K-Class is Beautyrest Black®s highest addition to the Beautyrest Black® collection and includes all the great features that you will find in both the L and C-Classes but also incorporates 3" of AirCool memory foam and a 1" layer of Nano coils - both of these layers you will only find in K-Class models.
