Situation: I am sitting in the center of a couch with a whiteboard to my left.
Alternative situations: I am sitting on the middle cushion of a 3 seater couch reading a romance novel as I wait patiently for others to arrive. Resting on a couch, I am pushing the chair in front of me with my shoe, while there is a desk on my right.
Question: Is the material of the couch the same as the material of the chairs in front of me?
