I ordered this chair since my mother has the same one. It helped me with my back pain. Unfortunately the screw holes on one arm don't line up with the screw holes in the chair so I've been unable to complete the assembly. Would like to send it back or preferably just get sent a new left arm.
I am a fairly big guy and this chair met my requirements for sitting comfortably at a computer/desk etc.. Moveable arms and height adjustments are a"must" and it has both and comfort!!!
