The Definition of Luxurious Comfort
by Jed HarringtonThe Beautyrest Black K Class Medium is the top Beautyrest mattress available in the top-tier Black collection. This mattress blends the best comfort materials available with an attention to detail and craftsmanship not many mattresses possess today.
A Near Perfect Comfort Level
The K Class Medium has a nice comfort level that’s designed to provide a blend between comfort and support. With a score of 5 out of 10 on our Comfort Scale (10 being the softest), this mattress is designed to provide great pressure relief and support, without sacrificing either.
The Top Support System, TripledThe T3 Pocketed Coil System consists of three steel strands, braided into one solid coil that absorbs energy, decreases motion transfer, and offers outstanding support, durability, and undisturbed sleep.
Cool Rest For A Brighter DayBlackICE 4.0 and RightTemp Memory Foam combine to ensure a cool sleeping space. BlackICE 4.0 uses four components to create a cooler sleep surface, while RightTemp Memory Foam pulls heat away from the surface and dissipates it over the course of the night.
