Product Description

The New Simmons Beautyrest Black K-Class Medium Mattress is more than a mattress, it’s a haven for deep, restorative sleep that inspires your senses.  The Beautyrest Black experience goes beyond mere comfort.  It creates a restful escape where sleep is the ultimate luxury.

Key Features of the Simmons Beautyrest Black K-Class Medium Mattress:

  • T3 Pocketed Coil®- Exclusively made for the Beautyrest Black mattresses, These high-carbon steel springs are triple strand-wrapped, pre-compressed and placed into a durable, yet soft non-allergenic fabric individually. What that means to you is increased strength, motion separation and conformability that creates indulgent comfort to withstand the test of time.
  • BlackICE™ 4.0- Introducing Beautyrest’s most advanced cooling cover yet. Through research and development, Beautyrest has created a mattress cover that cools in 4 ways. At the surface it is cool-to-the-touch. Just beneath the surface cooling materials enhance heat dissipation. SilkAir fiber prevents and wicks away heat build up. The addition of silver particles draws heat from your body so you can sleep cool and comfortable throughout the night.
  • Comfort Foam - Comfort Foam is made in varying levels of softness (extra firm, firm, medium, plush, etc.) to create comfort preferences for all comfort levels.
  • RightTemp™ Memory Foam- RightTemp™ Memory Foam is designed to cradle your pressure points while conductive materials in the foam pull heat away from your body to help you maintain an ideal sleeping temperature.
  • 2K Nano Coils- 2,000 micro coils are placed within the comfort layers to provide enhanced conformability and pressure relief for your individual shape.
  • Beautyrest® Gel Memory Foam – Is a premium memory foam combined with gel to provide incredible pressure relief and motion separation.
  • BeautyEdge® -Each Beautyrest Black mattress is surrounded in thick foam rails for additional firm, stable support around the edge of the mattress. Enjoy sleeping to the very edge of your Beautyrest Black mattress without feeling like your going to slip or roll out.
