I'm really liking this chair. I bought it specifically because the padding was thick and adding the arms is optional. (I built my chair without them to avoid snagging my clothes on the arm ends.) So far the padding is holding up well and keeping me comfortable. My only complaint is that the wheels are very slippery on my wood floor but I've learned to deal with that.
This chair fits me so much better than the other office chair I had. The arms are not as high (who knew that could make a difference?) and the back is more lumbar friendly. If it were just higher to accommodate my head it would be absolutely perfect!
