My 90 year old grandmother lives by herself in a house in which she needs to use stairs, but it's getting harder and harder these days. I know about electric lifts, but I recall a news story about a year or two ago in which a British teenage girl made a simple but brilliant invention: a track is posted on the wall above the stairs, and a large handle swings out perpendicular, and you grab onto the post/handle and pull yourself up or down the stairs. What is this invention and where can I get one online? Googling is hard because I can't think of what you'd call this...stair walker?
