I would give it 5 stars be wise it’s a great sturdy piece, but it took an hour to find which box had the instructions (P.S. it’s the largest box (not the long one, or the boxy one, it’s the large flat box.). It would have helped if the box said so.  Also, the instructions tell you to build the top bunk first and then the bottom.  This does not make sense and doesn’t work in smaller spaces and if you are building alone.  I built the bottoms first, then built the top bunk on top, it was much easier than having two completely built beds and then carrying the top bunk and placing it on the other.  If you have the space and the man power than great.  But I do not have that luxury.  Overall it took me about 4-1/2 hours to build, not counting the cleanup of boxes and foam.
