I’m only working a few hours a day right now so it’s hard to say if it will hold up to the busier seasons with longer hours in my chair; but only time will tell. For now the tailbone padding feels great! As for assembly… I will tell you that you MUST barely tighten each screw. This will allow you the”flexibility“ needed to line up all the holes on both arms easily. Then tightening them down after they were all in loosely one side was much too hard with the small provided Allen wrench so I pulled out my drill. ;) Oh and the wheels I tried pushing at first and they would NOT go in. I started screwing them in and they went right in. Overall it was an easy assembly.
I am really enjoying my new chair. The seat is deep enough that I don't feel as though I'm seating on the edge. I can adjust everything to make it feel like it was made for me. I would recommend it to anyone who has back problems.
