Dual Comfort. Zero Compromise. The Split Head Onyx Ice.
The Diamond Split Head Onyx Ice Mattress is the split-head version of Diamond's best-selling Onyx Ice — designed for couples who want individualized comfort without sacrificing the cooling and orthopedic support the Onyx Ice is known for.
Each side features Diamond's exclusive Graphene Bounce Foam and Responsive Gel Memory Foam for precise body contouring and a weightless feel, while the removable CoolTouch cover actively regulates temperature on both sides. The 6-inch orthopedic supportive core provides the stable foundation needed for proper spinal alignment and all-night pressure relief.
