The chairs themselves are stunning. The blue is slightly more vibrant in person but the same tone as pictures. They are very sturdy and well made. 
I am only giving 4 stars due to the terrible experience I had with the couriers. They called to agree a delivery slot which I accepted and then gave their drivers a completely different time slot. This left me wasting my afternoon and they arrived while I was out on the school run. The driver refused to wait despite me being 5 minutes away and left the large and heavy boxes on the door step. This left me to move the boxes myself with a bad back and 2 young and tired children getting frantic while I tried to do so.
Wayfairs customer service team dealt with the issue to my satisfaction but they really need to consider dropping XPD as a courier.
