Straight Stairlift is best used with 1 set of stairs. But sometimes families will add 2 straight stairlifts to the staircases that have a landing. But, you do have to go from one stairlift to the next to get to the top. Or a Curved Stairlift is a custom system that is one ride that will take you from the bottom to the top.
