Ensure cool, continuous sleep with the innovative Nectar 2.0 mattress. At the surface, a cooling cover with patented Tencel fabric is engineered to wick away heat and promote breathability. Gel-infused memory foam delivers powerful pressure relief. By redistributing weight, this high-density foam contours to your body for a cradling feel. Enhancing performance, a dynamic response layer offers additional support for long-lasting relaxation. A thick base of traditional foam creates a stable foundation to elevate the top comfort layers. Located on the bottom of your mattress, a lower cover keeps it in place to prevent the bed from shifting as you toss and turn. Plus, the Nectar 2.0 is a mattress in a box - easy to ship, deliver and transport! Forever Warranty
