Luxurious Comfort Defined
by Jed HarringtonThe Beautyrest Black K Class Medium is the top Beautyrest model available in the top-tier Black collection. This mattress blends the best comfort materials available with an attention to detail and craftsmanship not often found in mattresses today.
A Near Perfect Level of Comfort
The K Class Medium has a nice comfort level that’s designed to deliver a blend between comfort and support. With a rating of 5 out of 10 on our Comfort Scale (10 being the softest), this mattress is engineered to provide great pressure relief and support, without sacrificing either.
The Best Support System, TripledThe T3 Pocketed Coil System consists of three steel strands, braided into one solid coil that absorbs energy, reduces motion transfer, and offers outstanding durability, support, and undisturbed sleep.
Cool Sleep For A Brighter DayBlackICE 4.0 and RightTemp Memory Foam combine to ensure you have a cool place to sleep. BlackICE 4.0 consists of four components that create a cooler sleep surface, while RightTemp Memory Foam pulls heat away from the surface and dissipates it over the course of the night.
You Can Sleep SoundlyCertiPUR-US certified comfort materials are independently and rigorously tested to meet or exceed the highest quality standards.
Is This Good For Your Sleeping Style?If you want to get one of the best luxury mattresses available today, and you want something that feels not too soft and not too firm, the Beautyrest Black K Class Medium mattress may be the perfect choice for you. This mattress is made with the highest quality standards and comes complete with a 10-year warranty to ensure you’re fully satisfied with your purchase.
