We had a physical therapist come by the office and adjust everybodies chairs - the result was that sitting down hurt so badly I ended up standing all the time, that should be better than sitting down, and the best possible position for my back other than lying down. My feet wanted to murder me the first week, and especially the first 3 days, but once you get over it I highly recommend doing so - I actually don't have a chair at my desk anymore.
