The storage is HUGE for one, I can fit 4-5 pillows, as well as 10-15 throw blankets underneath. AND it turns into a twin bed?!? This sofa is pretty amazing. The color is like a dark charcoal grey with a bit of a teal tint. The only downside is the sofa is a bit stiff when you first sit on it, but after about a week it softens up. As for other reviews saying the back is not upholstered, I honestly don't mind because my sofa is up against the wall so you don't see the back anyway. Bottom line, if your sofa is going to be in the middle of the room, I would steer clear of this one.
