High-Performance Cooling. All-Foam. The Rally 3 Cooling Foam.

The Diamond Rally 3 Cooling Foam Mattress delivers the same advanced performance technology as the Rally 3 Hybrid — in a pure all-foam construction. Designed for sleepers who want a weightless, orthopedic feel without coils, the Rally 3 Foam uses Diamond's exclusive Hyper-Conductive Copper Bounce Foam and Responsive Gel Memory Foam to provide precise body contouring and active cooling.

The Performance Cooling Fabric cover keeps surface temperatures low, while the CertiPUR-US certified high-density foam core — denser than the industry standard — provides the durable, long-lasting support your body needs to fully recover overnight.

Key Features

  • Performance Cooling Fabric for a cool-to-the-touch feel
  • Hyper-Conductive Copper Bounce Foam for cooling and clean sleep
  • Responsive Gel Memory Foam for precise body contouring
  • CertiPUR-US Certified High-Density Foam Core (above industry standard)
  • All-foam construction — no coils, no motion transfer

Rally your best sleep — all foam, all night.
