The Diamond Plush Pillow Top makes it apparent how great of a job Beautyrest has done with the Harmony Lux collection. Packed with high-end comfort materials, an innovative new coil system, and a refreshing commitment to being eco-conscious, this mattress has become the new leader of performance at this price.
The Diamond is made almost entirely of premium materials that relieve pressure efficiently and feel soft and enveloping, including RightTemp Wave Foam, AirCool HD memory Foam, and Micro Diamond Memory Foam. RightTemp Wave Foam allows better airflow and uses carbon fiber to conduct heat away from the surface, while the Micro Diamond Memory Foam layer uses diamond particles to disperse the heat down further, for comfortably cool sleep.New T2 Coil System
The new T2 Pocketed Coil Technology, exclusive to Beautyrest, provides solid support with a conforming feel. In the center 3rd, there's a zone of T2 coils, which are like two coils woven together, to provide added support where most needed. This system is adjustable base compatible and excellent at reducing motion transfer.Seaqual's Fabric Technology
Every Harmony Lux mattress has a quilt made with Seaqual sustainable fabric. Seaqual is an ocean cleanup leader, transforming recovered ocean plastics into high quality fabrics. Each quilt not only looks and feels great, it promotes cleaner, healthier oceans.AirCool HD Memory Foam
This premium high density memory foam has an open cell design that makes it more responsive than traditional memory foam. It's able to conform to every inch of your body, providing amazing pressure relief.Premium Warranty Lasts 10 Years
The Diamond Plush Pillow Top is made to provide you with the support and comfort you need for over 10 years, backed up by the non-prorated warranty.Is the Diamond Plush Pillow Top Your Best Fit?
