Good chair for the price. Comfortable (though no significant lumbar support) and easy to assemble. This chair can only go up and down, you cannot lean back in it. It is basic but comfortable!
A couple of suggestions for assembly:
1. I recommend attaching the arms to the seat and back of the chair BEFORE installing the little adjuster on the bottom. That way, you can sit the chair's seat flat on the ground and have an easier time attaching the arms.
2. If you choose to follow the ordered instructions and attach the seat adjusted before attaching the back and arms, you should attach the back screws before installing the front screws. I had to unscrew the front ones in order to get the back ones in.
