Choose a used Acorn 120 stair lift for an excellent value on a dependable mobility aid even in power outages. The built-in DC battery draws a charge as the unit runs, keeping an energy reserve to ensure that you are never stranded on the lift or trapped on either floor of your home in the event you lose electricity or another emergency situation occurs. The swivel seat and foot rest can be folded up to conserve space when you aren't using the stair lift, and a sturdy, simple hand remote gives you complete control of your stair lift's travel.
