You have to read the instructions very carefully and put the chair together firmly. Don’t leave any nut and bolt loose. Don’t use other tools except those which are provided with the chair. Bolt every nut firmly. Once put together firmly I believe this is one of best chairs you will enjoy sitting in for hours.
I love my new chair. Most chairs tip me out because the seat slants so far forward. This chair is adjustable in the seat. It has a lot of other adjustable areas also.
I pick up the chair and built it. That part wasn’t hard but there was a piece of the plastic that goes on the chair that was broken and since that part wasn’t very necessary I just put the chair together. Overall it’s a nice chair and doing its job well.
