StairBusters.com just installed a new chair in my home and it has been such a big help! I was going to have them install a chair for me a while ago, but then I broke my arm and leg and wound up in a rehabilitation facility. My sister took care of it for me while I was away for almost two months. My sister had the company come out and she said she was very impressed by the company. They did the entire installation in one day. They even tested it out to make sure it ran properly. They offered to come back out and show me how to use it when I returned home. It is so simple that I did not even need to have them do that. I figured it all out myself. I use it quite a bit since I live up on the second floor which makes it more convenient. My medical insurance did not cover it, but I was very surprised that the cost was not as high as I thought it was going to be. It was a pleasant surprise! I highly recommend calling them. StairBusters.com is a great company to do business with and the product is wonderful.
