fold-down

I am curious as to where the bunk mattresses go when the TM is folded up. Also, in the demonstrator at the RV show, I noticed that the wardrobe cabinet across from the bath is basically just sitting on top the lower cabinet. TM also has an optional cabinet above the sink/fridge countertop. Does this cabinet need to come down when the TM is folded up? If it does, then I may not be wanting that as an option. On the 2720SD, there's a cabinet between the dinette and the fridge. Since the dinette moves inwards during folding, does that one need to be moved as well?
