The Diamond is possibly the best mattress to come out of the Harmony Lux collection. It's filled with materials that are innovative and high-performance, and it has a neutral feel that's amazing because it's not too soft, not too firm.
Surface Touch Gel Memory Foam, Micro Diamond Memory Foam, RightTemp Wave Foam, the Diamond has the best of the comfort materials. All of these layers provide exceptional pressure relief as well as efficient cooling, for more comfortable sleep. RightTemp Wave Foam starts at the surface, it's carbon fiber that draws heat away from the body, and the Micro Diamond Memory Foam features diamond particles that conduct the heat to enhance the cooling deeper down in the bed.New T2 Coil System
The latest innovation in support from Beautyrest, the T2 Pocketed Coil System, is featured in the Diamond Plush. It uses individually wrapped coils to provide conforming support, and has the new T2 coils placed in the center third to provide more support to the lower back.

I really liked testing the Diamond Plush. The look, the feel, and the cooling were packaged with solid but conforming support, and it was very comfortable. The partnership with Seaqual is also something I really hope continues to spread, because who wouldn't want a cleaner tomorrow?
