I use an old fashioned secretary's chair anywhere I have to sit for a long time. In at work they wanted to throw it out and get me one of those high back leather chairs and I told them NOOOOOO, don't touch my chair! The first thing I did when I got my job in the office was to move out one of those and put in my old timey one. It gives me great back support and so does the one I have at home. They were both made in the days before they decided to switch from four legs that lasted forever to five legs that don't.
