The Hälsa Sleep Mari Smoothtop Mattress features CoolTouch temperature regulating fabric crafted from special conductive yarns that actively move heat through the fabric. This maintains a cool, comfortable sleeping environment all night long. Graphene infused memory foam absorbs pressure so you can sleep undisturbed without tossing and turning, and regulates temperature so that you can get a deeper sleep by drawing excess heat away from your body. Responsive gel memory foam adapts to your body contours providing comfort and support, while offering proper spinal alignment and pressure relief. This also allows heat to move away from the body to keep you cool and comfortable. The Certipur-US HD comfort layer gives your body the support it needs for proper spinal alignment, and is made with open cell technology for lasting comfort. A high density orthopedic support core offers pressure relief and contouring, which is delivered with a stable high density Certipur-US certified foam core to provide support and comfort.
