I had concerns about such a large purchase online, but it was worth it.  Came quickly, easy to assemble (although I needed help moving the table- it's heavy!), and looks beautiful.  Absolutely no damage to any of the pieces.
I had the whole family over, it was perfectly comfortable to sit at the table gab half the night.  
The table without the leaf is square, and opens to easily seat 6 with plenty of room for dishes, etc. 
It's a very sturdy set, the finish is a beautiful black, with a slight wood grain look.
I will happily buy from Wayfair again.

Pros: solid, easy to assemble, gorgeous
Cons: none
