Medium 12.5-Inch Copper Cooling Hybrid Twin Mattress

Experience Cooling Comfort with the Diamond Nina Copper Hybrid Mattress

Discover the perfect balance of support and temperature regulation with this medium-firm hybrid mattress featuring a plush Euro-top design. Engineered with copper-infused memory foam, it actively draws heat away from your body to keep you cool throughout the night, while relieving pressure points for undisturbed sleep. The 740 individually wrapped dynamic edge coils deliver responsive support and minimize motion transfer, making it ideal for shared beds. Performance quilted heat and wicking fabric further regulate temperature by moving moisture away from the skin. At 12.5 inches thick, this mattress offers a buoyant, weightless feel thanks to its hi-definition transition layer. Made in the USA and Greenguard Gold Certified, it ensures a healthier sleep environment with low emissions. Elevate your sleep experience and wake refreshed every morning.
