Chair seems fine but I have not been able to actually test it out as the package was delivered with the wrong hardware. I did test the arms out and rotating them is difficult as if it’s put together very tightly - not sure if that will loosen with time but perhaps that means the arms won’t be able to stand upright as well 

Anyway, regarding the hardware issue, Wayfair accepted the replacement hardware request but said it would take two full calendar weeks for me to receive it.
