We received our sofa this morning. The delivery guys called me 30minutes before coming and dropped the sofa inside our house. 
Assembly was very easy. 
Color - The images online were a little misleading as a few pictures show white fabric and few show an off-white fabric. Like the other reviewer mentioned, it is an off-white with a greenish tint. I don't mind it so much. I have uploaded a picture of the fabric with a white paper to capture the accurate color balance. 
The legs are also greenish and not oak wood finish as mentioned in the description. I might change the color of the legs with a wood stain. 
The finish is awesome and the sofa looks very beautiful in my living room. 
Comfort - Its not a super cushiony/bumpy sofa. But i love the way it is strong and tightly stitched.
The cushions are lovely but i might use it with my other darker sofa. 
I am in love with wayfair already !
