This is a decent chair. It's not too difficult to put together and is plenty comfortable for me (6' 2" - 220). The problem is that the arm rests are put together using screws that are too short to keep the thing together. Like another reviewer my arm rest snapped off after about a week and a half of use. Incredibly frustrating. I now understand why the chair was so deeply discounted. The good news is you can fix this yourself if you want with some $2 wood screws from your favorite hardware store. They only need to be a bit longer to be effective (see pic attached - factory screw is on the left my screw on the right). Too bad the manufacturer couldn't figure that out. Definitely won't buy a Union & Scale chair any time soon.
Like other reviews have pointed out the head rest was extremely difficult to screw. The tension nob is impossible to adjust. The seat doesn't tilt with back.
