Typical double bed is one of those romantic ideas that is not always so fun in practice. I kind of wanted to see them throwing theirs out couple years later out of sheer frustration.. :p
I've never really had a good night's sleep in a bed with someone else if that bed had a shared structure. Not only do you get woken up in middle of the night when the other person shifts their weight, but also have to always stress about waking them yourself.
