I could not find the product locally that I was interested in so I had to depend on the sales representative to give me an honest answer. I was interested in the LC 525L because of its rating for tall people. They offered a footrest extension for an extra fee. Three different times I asked the sales person if the extension came up parallel with the leg rest, or stayed down below it. Each time he assured me that it went out and up, extending the chair. It doesn't (confirmed by a call to the factory) and by observation of my chair. The chair is well built and comfortable, but I was charged for something I cannot use.U.S. Medical is not interested in my problem. Returning it is not an option to me; I need the chair NOW, and I am totally disabled and could not package it up for return if I wanted to.
