Situation: I am in front of a brown chair and there are two red chairs behind me.
Alternative situations: I have my right hand on the arm rest of light brown chair in front of me to brace myself before sitting down on the chair, two red chairs are behind me. I have one hand on the arm rest of the brown chair in front of me to dray backwards towards the red chairs behind me.
Question: What is the shape of the bench on my left side?
