It was easy enough to put together and the chair would have been what I hoped for except for one thing- the knob that is supposed to loosen so the chair can tilt back is on so tight that it won’t budge, leaving the back rest in such a straight up position that it hurts my back. I bought this chair specifically for that feature only to have it not be functional. Very disappointing and it’s too late to pack it up and send it back.
