Stairlifts are motorized chair systems installed along staircases to help individuals with mobility challenges move between floors safely and comfortably. They operate on battery-driven or AC-powered motors and glide along straight or curved rails. Stairlifts include features such as safety sensors, swivel seats, remote call buttons, seat belts, foldable footrests, soft-start motors and emergency stop systems. They are widely used in homes, apartments and care facilities for elderly or disabled users.
