It was a two person job to assemble for me. Everything was easy enough to assemble but I did need a second person to hold the back up while I attached it to the arms. It's comfortable rolls smoothly and I love that the arms go up.
This is a very comfortable and stylish "gaming" style office chair. Smells leathery and judging by the squeaks when I shift my weight in the chair it probably is real leather. The "but" part of this is that this chair was diabolical to assemble! It should have taken maybe 30 minutes considering apart from the 5 wheels there's about 6 pieces. One of first steps of assembly is to put the wheels on the lower structure. Ok but going forward you are now adding pieces and trying to tighten bolts to a move structure! Also and most exasperating is towards the end. The instructions say to attach the arms to the seat and then attack the back to the seat/arms. This is nearly impossible: you are trying to aim and tighten bolts into the seat back blind. You can't see the point where the bolt goes in. After many frustrating attempts and about 30 minutes I unbolted the arms from the seat cushion and attached the arms to the back first and then attached that assembly to the seat cushion. Still a little tricky but at least then you can see where to tighten the bolts. I say all this as someone who generally enjoys assembling things and days before assembled a 8-foot wide wall unit with 5 glass doors 3 drawers and 5 non-glass doors with less frustration. If you have any doubts about your desire or ability to assemble something have Staples assemble it for you. Or at least have a helper (to help calm you mostly).
