Situation: I am sitting on a chair while facing a shelf at the front.
Alternative situations: I am sitting on a chair in the center of the room with legs crossed looking at the books on my bookshelf in front of me. After organizing my insurance file, I got up out of the chair to go file it away on the shelf.
Question: Is the material of the floor where I am sitting the same as the floor underneath the sewing machine to my right?
