Two of us put both of these together with the help of two ladders (two sizes).  Just a hint-put the middle arch together first, THEN place on the top.  Was difficult doing the directions way, but that may be because I am only 5'3" and my helper is 5'.  The main one opens perfectly and easily (locks well too).  The second one is a little harder to open, probably because it's on uneven ground and that gate was a tad bent on top, but we won't use that side as often (side towards neighbor's house, kind of a dead end but might use to mow that small strip of grass).  Each box was 80 lbs, so this should last a lifetime.  Can't wait for flowers and ivy to grow all over it!
