The Deluxe Knee Wedge is a versatile support to keep your legs in a comfortable position while lying down, helping to promote better circulation, and relieve tension in the lower back. The pressure is taken off sore knees, helping to reduce extension-related knee pain. Numbness and swelling in knees may also be reduced. The wedge may also be used as a backrest while relaxing in bed. Constructed of precision-cut, high-quality foam and covered in a removable plush cover for easy hand washing.
