I received the brown version of this futon last week.  So far, I am so satisfied.  My granddaughter slept on it for 3 nights and it was hard to get her to get out of it, as she said it was so comfortable.  It looks like a couch, not a futon, which is what I was looking for.  The dark brown one is called "charcoal" but it is not gray or black, it is dark brown.  Very rich looking.  

Pros: Easy to turn from couch to bed, with hidden legs in back.
Cons: Still has that "new" smell, even though the window has been wide open since being delivered.
