This chair was really easy to put together. If I can give one tip… put the base together separately from the seat and back. It’s much easier to line the arm up one side at a time then tightening it fully afterwards before putting it on the base. 

It’s very comfortable! My only negative is that it’s a bit too tall for me even at the lowest seat setting. I didn’t take that in consideration when buying it but all in all… great chair. I also wish I was able to recline it a little but that’s not a big issue for me.
