Situation: I am standing putting my hands on the backrest of the couch with a table behind me.
Alternative situations: I have both my hands on the backrest of the couch as I try to stretch my legs out behind me. I am standing behind the couch with one arm resting on the arm rest as I speak on my cellphone facing the bookshelves in front of me.
Question: What material is the big round table behind me made of?
