Used to have one of those years ago. It was purchased for one of the staff who decided they didn't like it, so that chair made the rounds of the office. Ended up in my office. I liked sitting in it, but my job required a lot of up and down and running out to the front counter. Extracting myself from that chair was neither effortless nor graceful. It lasted about a month before I surplused it.
