Stairlifts can be designed to fit your needs. Here we installed a curved stairlift that was made just for this home. It travels down the custom curved rail to a 180 degree turn at the landing and then down the stairs to the bottom where there is a 90 degree curved park position. With the park position, the chair is never parked on the stairs. The rail only takes 8 inches from the wall, and the chair remains level all the way up and down the stairs.
