Enhance your sleep experience with cutting edge technology with the Sealy Posturepedic Hybrid Copper Plush mattress. This half foam and half springs mattress combines body-conforming comfort with all-over support so you can relax and sleep well. The Copper Plush is a tight top mattress providing a thick, flat layer of upholstery for a soft touch. The tight top gives you durability and body support, preventing lasting impressions in the mattress. This mattress is covered in premium stretch cover fabric with soft-spun yarn and a gentle memory foam underneath. The side panels along the edge of the mattress help create a breathable border fabric that allows more airflow to help keep you more comfortable during the night. The Posturepedic Hybrid Copper Plush Mattress utilizes the Zone Sealy Embrace Coil, the premium version of the specially engineered encased coil system used for even more precise and exceptional support. The encasing allows each of the coils to move independently, for more targeted support and reduced motion transfer. There are nearly 20% more coils throughout the mattress to respond to the natural curves and alignment of your spine, for exceptional full-body support. The Copper Hybrid mattress incorporates the SolidEdge HD Premier System at a wider edge of 3 inches around the mattress so you can use the full surface of the mattress, as well as utilize the solid seating surface.
