The end result is a very nice counter stool, however the assembly while not complicated, was difficult because some of the holes did not line up properly, and the chair frame had a big dollop of grease that I found the hard way, staining my hands and the carpet I was using to assemble the chairs ...  It will take two people to put the backs on due to the angle that's required and the small space to work the provided wrench and Allen tool.  In the end I would buy them again, but be aware.
