Situation: I am sitting on the leftmost part of the bench getting my warm coffee from the coffee table while there is a couch in my around ten o'clock direction.
Alternative situations: I placed my handbag in front of the coffee table and behind me was the couch. I am sitting on the left side of bench facing the table having a hot coffee, the table is in front of me.
Question: What is behind me that can be used to lay down in or sit down in?
