The product is solid and well made.  Assembly of chairs a little fiddly and time consuming, but for the cost I think it is excellent value.  The table top does mark quite easily so we'll see how it fares over time.
Can't say enough about the excellent service provided by Wayfair.  As soon as I placed my order I was sent information e mails regarding delivery.  I was contacted by the delivery service and told the exact date and time slot - the furniture was delivered exactly when stated - the delivery driver even telephoned 15 mins before to advise delivery. 
Also excellent service when contacting customer service department - helpful, friendly and efficient.
Would definitely buy from Wayfair again.
