Key Features of the Simmons Beautyrest Black L Class Firm Mattress:

• T3 Pocketed Coil with Center-Zoned Construction – 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 create indulgent comfort to withstand the test of time.
• BlackICE with Plant Cooling Technology Introducing Beautyrest’s most advanced cooling cover yet. Through research and development, Beautyrest has created a mattress cover that cools in 4 ways. On 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.
