The first time I ordered this - there were no drawer guides in  the box.  The second time we ordered this, we were able to assemble it in about an hour.  Once assembled you can see that the bottom file drawer is only 11 inches deep and when you pull out the file cabinet it only pulls out 8 inches.  Yet the cabinet is 17 inches deep!  Useless.  It makes a good looking inexpensive printer stand, but if you need a file cabinet, you don't want this.
