The chair it self is great the assembly was a bit of a chore. The tilt knob doesn't get it to tilt very easily. Tilt is very stiff. Maybe over time it will loosen up?
I was in need of a nice desk chair and I saw that Staples had a selection of them already to go at the entrance to their store. I was able to sit in them and chose the one that I like. I decided I wanted the blue which they had in stock. I bought it and took it home right then and there. it took me a half hour or so to put it together but now I have very nice chair that I can fits my body. It was all a pretty easy process.
