All four chairs I ordered were defective (manufacturer drilled holes on one side but didn’t do so on the other side of the slates that secure the chair legs in place) and when I called wayfair for assistance to help assemble a poorly made product, I was told “it will cost you 500 for assembly”.  I paid 800 for these chairs and assembly is almost the same cost! Go figure.
