Sleep soothed! Sleeping on your side can cause pain in the knees and pelvis. With its ergonomic design, this memory cushion offers optimum comfort for side sleepers: it helps to correctly align the spine, stabilize the hips and support the knees during sleep. It helps relieve sore spots in the back, hips, thighs and knees all night long. Tapered edges give your knees the mobility they need for freedom of movement. The curved lower zone adapts more comfortably to your body. A practical fabric-covered elastic band positions the cushion perfectly and keeps it in place as you move about at night. Removable cover (machine washable at 30°C).
