Discover deeper sleep with the Omne Sleep Copper Infused Hybrid Mattress - a 14-inch profile designed to balance plush comfort with long-lasting support. This hybrid mattress brings together the best of foam and coil technologies to deliver cooling relief, responsive pressure relief, and reliable full-body support night after night. A phase-change cooling cover sits on top to regulate temperature, absorbing excess body heat and releasing it as you cool down, helping you maintain a more balanced sleep climate. Just beneath, a generous layer of copper-infused memory foam promotes airflow and contours to your body. A responsive layer of soft transition foam ensures smooth comfort, while individually wrapped coils provide adaptive support with reinforced edges to help you sleep comfortably from center to edge. Material: Polyurethane Foam.
