Took me and my 13-year old daughter 4-1/2 hours. It was not a frustrating process so I’m not sure if manufacturer improved packaging or ??? Found directions easy to follow— just need to really pay attention to the details in the pics.
That said, two pieces did not match the picture or were not pre-drilled correctly (one “C” didn’t match pic, and the holes for the top bunk dowels on “F” were in the wrong position) Other than that, everything except a few pieces were very clearly marked. The few that were not marked were easy to ID.
All in all, great project to accomplish with my daughter. My teen girls seem happy with it.
