I finally got a chair. A rolling office chair from staples. Some of the chairs there could be put together without the arms and some could not, because the arms were holding the seat and back together. I got one that could be put together without the arms and my 14 yo son put it together for me while I was running an errand. What a nice surprise that was to come home to! It's a bit short though, even at the tallest setting, so I put a thick cushion on it to boost me up a little.
