If hip problems, lower back and leg pains keep you awake at night, our Knee Pillow could help you to a better nights sleep. The most common sleeping position is on your side which can cause pain when one knee is resting on the other. The Knee Pillow gives soft gentle cushioning to your knees all night long. In addition, keeping your knees apart allows your legs to stay naturally aligned with your pelvis. Simply attach the Knee Pillow to either leg with the adjustable strap using the velcro fastenings. Removable soft poly/cotton washable cover.
