Box came damaged and had me a bit concerned.  When I opened the box and pulled out the first chair back, the top came off of the frame piece and so did the middle.  The top piece was also damaged where it met with the back frame piece.  I took pictures of each piece and what I did to fix it: wood glue and a bit of filing.  The second chair came out perfect and went together perfectly, however, the top piece came off last week (a month after receiving these products) and I used the same wood glue to put it back together and let it dry (again) for 24 hours before use.  This seems to have fixed the major issues.  There is still a part of the first chair top that is sharp from where it had broken off and I'd repaired it.  I'll get around to sanding it down when I find the time (probably about the same time someone catches their finger on it).  They're working well now.
