Overall it was fairly easy to assemble. It took me about 30 minutes to do it by myself.
You are supposed to put in 4 screws to attached the back to the seat, but no matter how hard i tried, I can only put 3 in. One of the holes seemed to be mis-aligned. However, having 3 screws in is still pretty sturdy....

You are given three black cones to cover the base rod... not sure if I was putting them on correctly, those three cones did not really cover up the base rod... But overall, I still like this chair.
