Yes, I do know. In the Quad, there are some beds that are bunked in a permanent way, while some beds are on frames that are low to the ground. Double rooms often have one of each; one bed is bunked (attached to the closet) and the other is free and low to the ground.
Aside from making a visit to the room that you are assigned, there’s really no telling which beds are attached when it comes to the Quad.
