Definitely need to do a better job with your packing.  This is the second set shipped to me because the first chairs were the wrong size.  Each time the packaging was terrible with boxes torn and open.  On this set even the screws under the chairs were missing in two of the chairs because they broke lose in the box and fell out of out of the rips in the boxes.  I had to go to the hardware store to get bolts and washers.  The packaging was sooooo bad that two of the chairs had deep indentations in them from the leg being jammed into it.  We used ice and a hair dryer to correct it.  I would have shipped them back but was tired of dealing with getting the correct chairs and shipping back and forth when I needed them.
