That would be an interesting trip to the hospital, "Well, she fell ten feet and cracked a rib, and the impact cracked my rib because I was laying on the floor. What part of this is confusing you guys?"
I've been trying to decide if they are or aren't, there are the same number of panels in the ceiling and the bed's ladder appears to be facing the same direction. I think the bottom picture just makes it look bigger than it is because it's inside, or on the top picture the size of the bed makes it look smaller
Edit: it has ventilation
