This stool was not that hard to assemble. I forgot to remove the protector cap, when I was done, I pushed the seat into the stand and the lever was not working. So I called customer service, got a live human being who stayed with me to give me ideas on how I could remove the plastic lodged inside. It worked and I am very happy with the stool, the service. The seat is a bit hard, but no worries, I will just put a small cushion to soften it.
