The stairs in this home in Golden, CO are a large radius curved staircase. That means that every stair curves and the stair lift rail has to be curved along every inch. This does take extra work, but the end result perfectly matches the wall and looks like a piece of custom trim along the stairs.
The lift will ride just a smooth in this configuration, but the lift does take a few week longer to create due to the custom nature of this curved stairlift.
I had a curved chair lift installed by Accessible Systems. I would use them again in the future as well as highly recommend them to family and friends. Everyone that I interacted with was extremely friendly and professional. The installers were awesome.
