Situation: I am sitting on a black coach under a bunker bed while facing the a chair.
Alternative situations: I am underneath the bed crouching to prevent bumping my head on the bed frame at top and looking straight at the chair. I am listening to some music while resting on the bed to the right of the wardrobe cabinet.
Question: What is bigger in size between the bunker bed above me and the couch that I am sitting on?
