I bought this bench for my parents for Xmas.  Now that it’s spring I’m trying to put this together.  Problem is, the sides will not stay on. No matter what I do.  I can not give this to my parents like this.  I’ve taken it apart and reassembled and still same results.  It’s useless!  This is a small example.  The other side, the entire back half won’t stay attached.  Soooo frustrating!
