The unit required complete assembly, but it was easy to assemble using the wrench that came with it. If the bolts are tightened properly it will seem sturdy, if not it would seem flimsy as some people stated. My only complaint is that one of the cheap plastic toggle bolts provided failed while I was installing the unit, this complicated everything. It would have been nice if they had included an extra toggle bolt, but I managed to get the unit installed. It looks very good and feels secure, I just hope the finish will hold up.
