I liked the chair and it works fine for my needs. I would like to point out that in a beginning of assembly we had an issue with the nut not wanting to go to bolt. We fount out what was wrong. If you look inside the nut hole you will see that one side is painted in black and another side is not painted. When you insert the nut and then tighten it, unpainted part should go first and black painted should be like outside.
About 4 main screws that hold the chair together
