It's definitely not the color in the stock picture. Not even a small hint of the color. I would call it very dark gray or black. 
The couch was easy to bring inside by myself and to assemble. It's a click in kind of assembly.  It is actually pretty sturdy while being lightweight at the same time. I am using it as my main living room couch and it looks pretty nice. I would recommend this sofa. 
The only complaint is the color, although many reviews stated it being a darker color- I just didn't realize it would be black. I'm still happy enough with the purchase.
