Weightless Feel. Orthopedic Support. Ice-Cold Comfort. The Onyx Ice.

The Diamond Onyx Ice Mattress is a premium foam mattress engineered to keep you cool, aligned, and pressure-free all night long. At its core is a 6-inch orthopedic supportive base that promotes proper spinal alignment and delivers the kind of deep, stable support your body needs to fully recover overnight.

Above the core, Graphene Bounce Foam and Responsive Gel Memory Foam work in tandem to contour precisely to your body's shape — giving you a weightless, cradled feel without the sinking sensation of traditional memory foam. The removable CoolTouch cover actively regulates surface temperature, so you never overheat, and it's easy to remove and clean whenever needed.

Key Features

  • 6-inch orthopedic supportive core for spinal alignment
  • Graphene Bounce Foam for responsive, cooling comfort
  • Responsive Gel Memory Foam for precise body contouring
  • Removable CoolTouch cover for active temperature regulation
  • Optimal pressure relief for back, hips, and shoulders
  • Available in multiple sizes

Sleep on ice — wake up refreshed.
