very easy to put together since we had two sets of hands  (but could do it solo without any trouble)  used a drill and hex driver bit instead of the provided allen wrench---I think that would have been a wearout
used wood glue on the pegs in addition to the screws and they are STURDY 
minor complaint about  the 'buttons' to cover the screw holes: a couple were the tiniest bit too small and kind of sunk down into the holes--doesn't bother me than much; doubt anyone would ever notice except me   recommend highly
got them for tall bar on side of kitchen island--perfect height  VERY PLEASED
