Zero Gravity lift chairs are a Golden Technologies specialty. Like infinite position lift chairs, the backrest and foot\rest operate independently and give the user greater control, but a Zero Gravity chair can also elevate the feet above the head and heart to create the Trendelenburg position, which can promote better blood circulation in people with hypotension (low blood pressure). If you have questions about lift recliner positioning or would like to know more about a particular lift chair you see here, please call our lift chair specialists at 1 (800) 252-2779.
