Struggle to get the screws aligned still not strong enough to get the back arm rest attached to the back of the chair. However posture corrected and comfortable without an extra cushion.
I had trouble getting the 4th arm screw into the chair. The first 3 worked great. Nthe 4th screw would on go in half way. The hole for the screw was stripped. No screw went in all the wat. I’m using the chair because at least 3 screws supported the arms. Love the chair.
