if there was a little written instruction with the diagram, it would have made it even more easier. i actually had a piece upside down, and had to take it apart when i realized. it's tough because you are building it upside down or from the bottom at times, and you can get a little confused because the piece will fit both ways. maybe just helpful hints, or a reminder footnote, telling the person to be sure they notice this when assembling this piece! otherwise, my son and i had little problem. thanks, chuck panzica ( lynn's husband)---also, we thought the headboard came with it, and were a little upset that it was extra $$$. the picture shows the box with the headboard and the description is sketchy, unless you are a professional bed-builder. we couldnt use his boxspring with the headboardeither, it made the bed too high and it blocked some of the shelves, but that's what the box was for, just not as comfortable as a box-spring.
