Once this chair is assembled it’s gorgeous. Everything about this chair feels and looks of high quality. The casters are smooth and rotate easily; the brass is tasteful, heavy, and beautifully finished; the chair is soft and comfortable to sit on: the adjustable height mechanism is easy and smooth to use (hydraulic). Like I said - this is a gorgeous, comfortable and high quality chair. The only thing is the assembly. It would have taken me 30 minutes max to assemble this chair. It ended up taking about 90 minutes instead because of one thing only. The screws were difficult to engage in a way to tighten. It was so frustrating that I just wanted to give up at a certain point. But once I finally assembled the chair, it was really rewarding. :)
