We ordered six of these chairs so I have had some experience putting them together. The instructions are complete and it will take some time to build each chair. However, their construction is super solid with heavy bolts keeping it together. Two of the bolts did not thread easily into place so they had to be painstakingly tightened with the supplied allen wrench (a quarter turn at a time). In the places were screws are required, it is super important to make sure that the supports are firmly in place before screwing. Two chairs were slightly off-level which was corrected with felt pads.
