DMI Ortho Bed Wedge Leg Rest Cushion Pillow If you suffer from back pain, knee pain, varicose veins, phlebitis or restless legs, this cushion could help you achieve a more comfortable night’s rest. Keeping your legs elevated at night can help to take pressure off your lower back, legs and knees. This supportive foam pillow will help elevate your legs at the proper angle so you won’t have to resort to using pillows not designed for this purpose. Set the cushion at the foot of the bed and rest your legs on it. The bed wedge includes a removable blue poly/cotton which is machine washable.
