Select a used Acorn 120 unit for the best price on a reliable stair lift even in power outages. The built-in DC battery builds up energy during use, storing reserve power so that you're never stuck on your stair lift or unable to reach your desired floor in case of a power loss or other emergency. The swivel seat and foot rest can be folded up to make room for foot traffic on the stairway, and the easy to use hand remote puts you in control of the stair lift's every movement. 90-day parts-only warranty included with purchase at no additional cost!
