Situation: I am sitting on the rightmost side of the couch with a couch in front of me and a couch to my left.
Alternative situations: I am taking a nap on a couch, near the wall, while there is one more couch in front of me and another one on my left. I sat down on the couch to relax and there was another couch right in front of me.
Question: How many rows of seating are there in the room?
