Situation: I am picking up the pillow on the couch with two other pillows on my left and there is an armchair in my five o'clock direction.
Alternative situations: I am taking out the pillow from the couch on right side before I take a seat on the couch in front of me. I am fluffing the pillow on couch on right side before sitting down on couch in front of me.
Question: How many armchairs are behind me?
