It's okay for a basic office chair. The back doesn't stay in place but overall the many adjustments are nice. Don't see it holding up long term but maybe it will surprise me.
I have had the first chair for about 5 years when the model first came out. I just bought this second one to be sure I had a spare because I like it so much - still in the box in the closet. Obviously the first is still going strong my daily chair where I work on my computer and even eat dinner off a tray.
