The box was missing an “A” bag of bolts.  The “B” and “C” size bolts came in the proper quantities.  I am contacting Customer Service for the missing bolts.  Also, and the worst issue is that,  the stitching on 3 of these chair backs is in line.  On the 4th chair the back stitching is MUCH lower.  If I didn’t have to request another seat and a bag of screws I would have given it 5 stars.  Decent product, factory lacking Quality Control.
