Power chair beware

This chair I'm in the one that I'm trying to survive in for one more year when I'll be eligible to get another chair is literally driving me crazy. It just seems that each time I get the chair back from the shop within two or three days something else happens and the whole process started over again and now it's even more dicey because the wheelchair shop that I use where I bought the chair they don't refuse to work on the chair but they say if they do work on the chair it'll show the manufacturer that something's been done to the chair and they'll extend the time that I have to use the chair even further. This of course leaves only the folks over at ucat and there's somewhat catches catch can. They always come through for me but it's always on their schedule. Today I've used the chair quite a bit as always and I was in my room this afternoon leaning back in my chair as if to take the weight off my butt which is an issue I'm dealing with right now- - trying to keep as much weight off my butt as possible to keep pressure sores away. Anyway I was lying back and as I was Rising up in my chair I heard a couple of snaps or cracks and all the sudden I was listing significantly to my left. Anymore listing and I would be falling out of my chair luckily I was strapped in but I was obvious in a chair that no longer was functional. Fortunately, I have my backup chair and as much as I wouldn't want to be in it any longer than I had to be I would transfer over to it and in fact that's what I was going to do. I called my health care provider, Melissa, and she was willing to come right over and sling me up from my chair that I'm in into the other chair. When Melissa finally got here I decided I would try to run my chair through the cycle again just to see what happens and to see if she could possibly see what is wrong with the chair. As I cycle my chair through the system I felt alert- I didn't hear any cracks or anything - - but the chair went back to setting itself upright again and I couldn't figure out what would happen all I know is it seems to be working again now so instead of transferring into my other chair of elected to stay in this chair but once again I'm in a chair that I don't really trust now the chair could go funky on me any moment anytime and I just have to hope I can get through this long enough until my chair isReplaced at some point in time.
