Cheap construction. Nearly broke the thing unfolding it. Had to screw the arms back in because if you open it too wide it applies pressure to the arms and pops them out of place. Also these are terribly uncomfortable. They hit the bottom of your thigh in a bad spot. Kind of hard to believe someone at the manufacturer didn’t just sit on it and say “we have to fix this…” I would shy away from these chairs. Or buy them lightly used from me.
