My buffet just arrived yesterday.  Like other reviews have said, it comes completely assembled except for the feet, which we choose not to use since the buffet is taller than we thought it would be (be sure to check height).
We ordered the gray which reminds me of a diftwood color.  It is more of a gray tan color with a hint of green.  It is not a true gray.
The piece is very heavy.  It took my husband and my 19 year old son to move it into place.
I love this item!  It is very nice quality, just like you purchased it from a furniture store.  It is well worth the money I paid!
The only things that would have made it nicer, is if there had been lights where the glass doors are.  I am going to add battery LED lights so I can have it lit up on special occasions to show off my china piece, and they velvet lining the drawers is kind of thin, a thicker piece would be better.
Overall a great item!!
