As the premier offering in Beautyrest's most advanced collection yet, Beautyrest Black® K-Class Firm Pillow Top Mattress now offers up to 21% more support where your body needs it the most and 18% more cooling power with new plant-based technology. In addition to Beautyrest's support and cooling systems, Beautyrest Black® K-Class includes comfort, pressure-relieving, and support upgrades as well as 10 times more memory foam compared to Beautyrest Black® L-Class and C-Class models for Beautyrest's most comfortable mattress ever. These innovative features are paired with an all-new modern design to create a first-class sleep experience that will leave you feeling invigorated to take on your day.  Features: Top-Notch Support Beautyrest's premier support system, featuring our T3 Pocketed Coil®, has been redesigned with center zone construction to help provide targeted support where you need it most. The patented triple strand pocketed coils provide enhanced support and absorb energy to reduce motion throughout the night to help you stay asleep. We've also included our Self-Response™ Latex, which ensures individualized support for different parts of your body. Lastly, 2000 micro-coils add an additional layer to our Premier Support System and provide precise conformability. Temperature Management Beautyrest's new temperature management system, designed with plant-based cooling technology, helps keeps you cool and comfortable as you fall asleep and throughout your night. Memory Gel Foam for Maximum Comfort Unlock Beautyrest's most robust pressure relief system with up to 10 times more memory foam than Beautyrest Black L-Class & C-Class models. AirCool® Memory Foam is a luxurious memory foam that provides personalized pressure relief for freedom of movement for both you and your partner while SurfaceTouch™ Gel Memory Foam works directly under the sleep surface to quickly unlock advanced pressure relief from the moment you lie down. We also use a luxurious layer made with silk, alpaca, and cashmere for unmatched comfort and breathability.
