Pretty easy to assemble. You could also watch a YouTube video before doing it. The only glitch is that the chair stuck and didn't move up or down. I almost wanted to return it. But sitting hard on it for a few times magically made the gas cylinder work.
This chair was very easy to assemble and it is quite comfortable now that my office consists of an old bridge table in a bedroom. It is ergonomic and my back feels so much better now. I highly recommend it.
I bought this chair for my office. It looks expensive and is vert comfortable to sit in for one month if that. I am now sitting on the metal that once was covered by the so called chair padding. If you are looking for a chair that looks nice this is a good buy. If you are looking for an everyday chair to actually use do not buy this chair.
After sitting in 20 different chairs in the store I went back to this one--my first pick! Comfortable roomy seat fully adjustable so I could set up just how I want. Cushiony yet sturdy enough and was easy to follow directions for putting it together myself. I would recommend it for sitting at a desk for long periods of time.
