The Nouhaus Ergo3D chair is really great.

1. The chair was devlivered in excellent condition in a timely manner.

2. Everything needed to assemble the chair was in the kit. It even included one extra of each size screw needed--what a nice thought!

3. It took me about an hour to assemble--but I have assembled things like this before, so it was not a new experience. The most important thing is to not tighte4d the screws for the arms all the way--you will want to adjust them to suit your build (size) once you are able to sit in the chair. However, this means you do have to lie on the floor and look up to finally tighten them.

4. This is a very comfortable chair. I am pleased with both the air cylinder that adjusts the height and with the adjustable arms.

All in all, a great product. Well worth the cost.
