The Pinacle of Luxury

by Jed Harrington

The Beautyrest Black K Class Medium is the best Beautyrest mattress available in the top of the line Black collection. This mattress combines the best comfort materials available with an attention to detail and craftsmanship not many mattresses today.

A Near Perfect All Around Comfort

The K Class Medium has a fantastic comfort level designed to strike a blend between comfort and support. With a comfort scale rating of 5 out of 10 (10 being the softest) this mattress is designed to provide good pressure relief and support, without sacrficing either.

The World's Premier Support System. Tripled

The T3 Pocketed Coil System uses three steel strands, braided into one solid coil that absorbs energy, reduces motion transfer, and provides outstanding support, durability and undisturbed sleep.

Cool Sleep For A Better Day

BlackICE 4.0 and RightTemp Memory Foam combine to provide an exceptionally cool sleep environment. BlackICE 4.0 uses 4 components to provide a cooler sleep surface, while RightTemp Memory Foam pulls heat away from the surface and dissipates it throughout the night.

Rest Easy

CertiPUR-US certified comfort materials are independently tested to meet or exceed the highest quality standards.

Is This Good For You?

If you're looking for 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 perfect for you. This mattress is made with the highest quality standards and carries a full 10 year warranty.

Best mattress and well worth the price
Although this mattress was pricey, after using it for the last 6 months it has been worth it. After years of poor sleep on every kind of mattress, I assumed I just wasn't destined for a decent night sleep but our mattress had reached it's end and it was time for a new one. After lots of research and reading reviews, we went to a local store that carried this mattress and were amazed at how comfy it was. I'm a side sleeper and my wife is a back sleeper and we've both gotten good nights' sleep. The mattress is well constructed and keeps you cooler at night. Thanks Beautyrest for a great product!

Just Right
BEST Sleep Ever!!!
OK, we spent a WEEKS looking at mattresses. VERY hard to find a high quality mattress that isn’t too soft (which ultimately gives backaches) and a stiff-Board feel. This mattress is neither! It has enough complex padding and substance to give even the pickiest people (like us!) a WONDERFUL night’s sleep! I have both RSL Syndrome AND lower back/hip PAINS THAT LITERALLY DISAPPEARED on this mattress! THANK YOU BEAUTYREST TEAM !!!

Firm
We have had the Mattress for about 3 weeks . First impression so far is it is very firm maybe even hard . Seems like the Mattress is breaking in but still very firm. My wife and I sleep well . But I sometimes wake up with a stiff back . We may swap for the plush
