Here is a great picture of Elizabeth in Highland Ranch, CO as she rides her custom curved chair lift from the park position at the bottom of the stairs to the custom bend and a second curve at the stairs wind up to the second floor bedroom. This lift matched the corners of the wall, and goes from top to bottom in less than 40 seconds. The chair of the chair lift swivels at the top and creates a safe exit position. This is the only time that the chair blocks the stairs, and provides extra protection as you stand up. Then the seat swivels back and folds up tight against the wall.
