My contractor was awesome. But Handy had originally sent him to my house to assemble 1 chair (for 45 min/$15). He arrived to my order (4chairs) and was concerned ( legitimately) about assembling 4 chairs for only $15. (He does not get paid for time, travel, or maintenance/replacement of tools.) 
I immediately called Wayfair and Jenna was super helpful. She got it straightened out and he got paid for 4 chairs.
I’m so impressed with Wayfair customer service that I’ll DEFINITELY shop again! Thanks to Carson for assembling my chairs very well (professional, quick, friendly, cleaned up afterwards...) and to Jenna for solving the problem!
