Straight stair lifts are motorized chairs that move on a rail that is mounted to the treads of a straight stair. The stair lift user must be able to get on and off the chair independently. A stair lift is also called a stair chair, a chair lift, or a stairway lift. Features include built-in safety belts to make the ride a safe one, a swivel seat, and a fold-away seat that enables traffic in the stair way and surrounding area to flow smoothly with no obstruction. The easy to use controls are sensitive enough for those with dexterity issues, and remote control options make transferring the lift from one level to another very convenient.
