A fantastic stairlift that only occupies 10.5" of stairwell space is the Pinnacle. Easy and secure entrances and exits are made possible by a swivel seat at the higher landing. The seat has a full-sized backrest that is fully padded, as well as a retractable seat belt for safety. For a quiet and comfortable ride, the Pinnacle features a helical worm gear drive system. Because there is no need for grease or lubrication thanks to a nylon polymer gear rack, the lift requires no maintenance and is simple to clean.
