LEG SEPARATOR KNEE PILLOW MEMORY FOAM. Sleeping or sitting can be difficult for those with back, leg, hip or joint pain. A knee pillow, when placed between the legs, keeps your legs, hips and spine parallel and aligned. This results in improved circulation and decreased pressure and strain on those areas. The high quality memory foam reacts fast to provide instant relief and comfort and provides slow memory foam recovery for longer support. The removable soft polyester and rayon cover zips off easily for machine washing. Hypo-allergenic. Dimensions: 10 1/2" Long X 8" Wide X 7 3/4" High. This product is returnable if it is unused and sealed in its original packaging.
