Situation: I am facing a mattress across the room and there is a cabinet on my right.
Alternative situations: I am standing to the left of the cabinet, my right hand feeling the wooden top of the cabinet and the picture frame is on my left side. I am leaning on the handrails of the stairs, my right hand is on top of the cabinet to my right side.
Question: The mattress in front of me has a color resembling that of charcoal; true or false?
