Next time I will pay the extra to have it assembled. The hardest part was putting the back on. Trying to line up the arms with the holes on the back was not easy. Had to loosen the arms a few time to accurately align with the back.
So far I really like the chair especially the width. I have very wide shoulders and too many seats now come with "wings" that my shoulder blades end up resting on and they are not comfortable at all. Now I can do my work and not get distracted by discomfort. Also seems to be well made.
