If you suffer from back pain, knee pain, varicose veins, phlebitis or restless legs, this cushion could help you achieve a more comfortable nights rest. Keeping your legs slightly elevated at night can help to take pressure off your lower back, legs and knees. This supportive foam cushion will help elevate your legs at the proper angle so you wont have to resort to using pillows not designed for this purpose. Set the cushion at the foot of the bed and drape your legs over it. The cushion includes a removable blue polyester and cotton machine washable cover.
