Large couches are an amazing addition if you have a big family or often entertain guests. Not only can they be styled like this, where the back of the couch acts as a half wall for a walkway, but they can also be pushed into the corner of a room, so you have more movable space for any impromptu dance parties. The light gray shade here is the perfect pairing for the sage green walls and white board and batten wainscoting along the room’s back wall.
