FYI, these are a pain in the backside to put together and they wrap it up in so much material.  I believe the screws were too long and I had to drill holes prior to putting in the screws.  The directions made no mention of this.  This is only a quick fix.  My review is very honest and I just want people to know it is a pain to assemble with the screws.  I am mechanically inclined, however, the design is impractical.
