I will need new parts because of the poor quality of this material.  Nails ripped right through while constructing.  As you can see in the picture, the only way I could semi-complete this for my daughter with disabilities to use in her room in her assisted apartment was to prop it up with a book to bring the left side high enough.  The nails on the back piece (7) ripped through both holes so there is no way to keep this stable.  I cannot deconstruct this totally to send the whole thing back because it is just too much on the already sore wrists.  I am requesting at least the back piece and the left side piece.  I expect that while moving it around the same thing will happen.  So, I'd love to trash the whole thing if you give me my money back.
