I think your quality control needs an overhaul or closer supervision.  The love seat base and 1 of the chair bases were damaged prior to arriving and need to be replaced pronto.  I closely looked over the boxes before signing the bill of lading by Federal Express, and, there was no visible box damage, hence concealment.  There also were no washers included with the packaging. Just screws and bolts.  Please let me know via email or direct contact as to when I can expect the replacement bases and appropriate washers.  Advance thanks!
