Zero Gravity lift chairs allow you to achieve nearly any position imaginable. Customize your seating position to suit your desired comfort level perfectly - you can even use a Zero Gravity chair to achieve the medically beneficial Trendelenburg position, which elevates the feet above the heart. This position improves respiratory and circulatory capacity and function, and is often recommended by doctors to people who suffer from chronic back pain, hypotension, or edema. For additional information about any Zero Gravity lift chair you see here, we invite you to call our lift chair specialists at any time!
