I'm enjoying my new chair. Hated my old chair. My back was always sore and the arms were horrible. Not so with this chair. It's all adjustable. So I can make the height back support and headrest fit me perfectly. I also like the white and gray that goes with my office. The only draw back is the white which I love but it might tend to get dirty. Especially where I put my feet on the base. That's totally me and I still love the chair!
This chair was most practical for vertical movements and stability. My only negative which could not be topped by any other chair available was the tilt locking positions. There are set positions. However it was a smooth device. Another chair was more costly that had locking tilt at more varied positions including custom.
