Featuring Qube Cell Layer - a breakthrough sleep innovation, Duroflex Quboid Mattress is foam engineering at its innovative best. Built using a combination of high density and high resilient foam, this mattress is designed to give you the twin benefits of plush feel and perfect body support, with the best air circulation because of the unique cube structure inside. Cuboid also features our signature 3 Zoned Copper Infused NRG Layer that enables better blood circulation and muscle relaxation for the most enriching sleep. This exclusive layer comes with Copper-infused gel foam copper infusion that draws heat away from the body for a cooler and more refreshing sleep. Copper being naturally antimicrobial also makes sure your mattress stays safe and hygienic. All this is enhanced by our Anti Stress Technology in the knitted fabric, designed to repel negative ions from your body, leaving you positively energized. Sustainability Score: Quboid is made using fabric comprising 40% recycled yarns (from used PET bottles) along with recyclable packaging.
