Well ... I have received 1 box out of 3 (3 chairs) even though the system sais that the whole thing was delivered. No one in customer service could really tell me what is going on, I have to wait 5 more days to see if the rest will come in, they cant trace the rest of the package. 
As for assembling the chairs ... Its quite a pain as many holes do not allign, you end up having to force and bend the frame to get the screws started. Once assembled, they look nice, but they feel very very cheep. I am not sure if they will last long.
Finally, I must say that the price is way exagerated for the quality you get. So far, I find products sold by Wayfair very expensive.
