Steven, I don't have medicare. My chair is wonderful now, but Phil has done a lot of work on it--changing the way the legs worked is one thing he did. It is also not reliable with the electronics. It's an Invacare T D X-SP, and while I do love it when it's being good, I'd get a Permobile if I were to do it over. All these chairs have sensors which need to be removed unless you're inclined to be too adventurous. I've had mercury sensors and one other kind removed, but there's still something left, which I'd like gone!
