I love this butterfly headboard! Nice finish, great quality, packaged very well. Instructions were confusing. I had to stare at them for awhile before I made sense out of them. Im guessing the job of creating Instructions doesnt pay well because almost every set of instructions Ive encountered over the years were poorly written. They always like to combine 10 steps in one diagram with arrows all over the place. Anyway... If mounting on a queen size frame, you dont need the 2 square brackets. They are only for a smaller, full size frame.
