ultra plush pillow top

There are core features in the K-Class that this collection shares with the rest of the Beautyrest Black collections. All of the mattresses use the T3 Pocketed Coil design spring system.  The coil design is the Beautyrest's most advanced and they only offer it on their luxury Black mattresses. Also, these mattresses use a top foam layer they call BlackIce 4.0.  This material is the latest in cooling technology.  If you put your hand on the mattress you can actually feel the cooling ability.  A cool mattress is important to sleeping well. The K-Class also has another layer of advanced cooling technology called RightTemp memory foam.  The formulation in RightTemp does, and the name suggests, help maintain an ideal sleeping temperature. What really makes the K-Class Collection unique in its features is a layer of nano-coils.  The layer of 2,000 small coils helps to give luxurious conforming and support working together with rich layers of super soft foams.
