Core Products Knee Elevator

This simple positioning wedge is an excellent support for the reduction of circulatory problems, knee pain and low-back pain. Doctors frequently recommend sleeping with your legs elevated to improve overall circulation.  Leg elevation also reduces stress on the lower back when laying down. Combine this leg wedge with a quality Core® cervical support pillow and you may have the perfect night's sleep. Made of cut foam and covered with a cotton/poly gray deluxe fabric.
