The Contour Products cloud mattress pad is ergonomic and orthopedic in design and unlike other pads, has an internal layer of support foam to provide extra support to your lumbar region. With 3 layers of memory and support foams, each layer is designed to provide Full body support plus targeted spine and lumbar support, while cradling you in memory foam comfort. The top layer of this bed pad is plush memory foam and molds to fit your body's every curve and helps to relieve stress and pressure. The second insert adds lumbar support for your waist, lower back and hips to support your spine in its natural position. The third base layer provides overall cushioning and ensures that the mattress will not bottom out beneath the weight of your body. Pressure studies demonstrate that body weight is more evenly distributed on this pad than on an ordinary mattress, minimizing pressure point build-up and tossing & turning. Additionally moving x-rays show how the pad maintains proper spinal alignment to help provide a great night's sleep. Since the introduction of our first product in 1991, Contour Products has emerged as an innovative leader in the ergonomics industry, developing unique products that meet everyday comfort and support needs for people of all ages. Our products help to properly align the body for better rest at night and comfort during the day for improved total well being.
