The CopperCool technology in the mattress wicks away excess body heat allowing you to sleep cooler throughout the night. When you are laying on your mattress your body will naturally compress the foam and in result the copper and gel particles infused throughout the top layer of the mattress start to coalesce together allowing for the heat to travel away from the body, from particle to particle. Our foam components also have higher airflows than most mattresses on the market today allowing for better heat dissipation.
