The Beautyrest Harmony Lux Diamond Medium Pillow Top is an outstanding firm mattress that has the initial contouring feel of a pillow top. With more premium materials than any other mattress in its class, it's arguably the best firm pillow top available right now.
RightTemp Wave Foam, introduced with the Harmony Lux collection, uses carbon fiber to help regulate body temperature and is channeled for better airflow, for more comfortably cool sleep.MicroDiamond Memory Foam
Previously found only in the ultra premium Beautyrest Black collection, Micro Diamond Memory Foam is used in the Diamond. A top of the line comfort material, it provides outstanding pressure relief, which helps you sleep soundly, and it uses diamond particles as a conductor, helping you sleep cooler. It works very well with the Right Temp Wave Foam which uses carbon fiber to reduce heat.New and Improved T2 Pocketed Coil System
The Diamond features a best in class coil system, the T2 Pocketed Coil Technology, which uses two coils woven together to provide extra support to the lower back area. An individually wrapped system, it contours to your body, but it's made of high carbon steel so it's incredibly durable and supportive. This system represents a significant jump forward in mattress technology, and is also adjustable base friendly.Seaqual's Eco-Conscious Fabric For Quilt
