More Information

The industry’s only 600 lb. capacity stairlift, the Pinnacle Heavy-Duty Stairlift combines comfort, mobility, and convenience.

The seat (18.5" W x 14" D) features extended armrests for more comfort, and both seat and backrest (17.6" W x 17" H) swivel for an easy, safe entry and exit away from your staircase. The retractable seat belt secures you for a safer trip up and down your stairs. The footrest houses a sensor that will stop the lift and alert you audibly if it meets an obstruction.

The stairlift operates without grease or lubrication to keep your home cleaner for you and your pets. The motor moves up to 14 feet per minute, and in a power outage, backup batteries provide up to 60 trips.
