I've tried to contact Wayfair by computer but can't.  I ordered the rockers and one rocker they sent two short pieces of wood as noted in picture.  I should have gotten one short piece of wood for the bottom back and one longer for the front bottom of rocker.  Also one of screws were bent and need a new screw.

Up date:  Wayfair's customer service is wonderful!  They are shipping the parts needed.
