There are some parts I would like to talk about.
1. Poor delivery communication : if you live not at first floor or a townhouse, you will never know will they deliver to your door or not. Because you need to contact Fedex by yourself, and FedEx requires to have a Shipping number first before you add any delivery instructions. Even though FedEx say no, during that time, Wayfair was already not available to cancel the order.
2. Compared to the date they promised when I checked out, they are 1 day late.
3. The couch itself is easy to assemble. And the color is as expected. 
4. The couch is really firm. For now, it is as hard as a rock. Hope it will improve after couple days. Otherwise, I can imagine an unhappy face from anyone who sleep on that.
