Got one of these from here a few months ago and it is a very SOLID chair. Definitely office-grade, not like the bargain ones of similar price you see at local stores or big-box places. Heavy metal construction and looks built to last. Also fairly attractive (for an office chair anyway). I hate the plasticky ones you see with huge tufted fake leather that make you feel like the top executive at a company that could only spend $89 for their top executive chair.
Ha ha. I never thought of it that way!
I have lots of these at work; they are oddly comfortable and roll well. The height adjuster can be a little quick on the trigger, but I haven’t had any compression issues with them.
