I have a concrete floor in my office in a building that is less than two years old so its fair to say the floor is goodthe wheels that come with this chair became pitted and wore down or clunky within weeks. Other than that Ive since purchased aftermarket rubber wheels and have a stellar chair for my desk that I spend on average 6 hours a day spinning around at mon-fri. Btw Im 64 and 240#. Great chair bad wheels which is a minor repair in my opinion to remain comfortable in a quality chair.
Four stars but doesnt roll so good on concrete.
