One of the chairs was poorly manufactured; and the fabric looks wrinkles in it, cause it wasn't set to the matting properly. 
I'm STILL waiting for a reply from Wayfair, and I contacted the online-customer service days ago.  Couldn't get a real person on the phone, cause of the Covid-19 situation; but I should have heard back already.  The products also took so long to be delivered.  I purchased the extended warranted on the chairs.  So I hope that insurance date gets extended too, based on the replacement/repair arrival date.
