Mmm, I do like my current double bed ♥ (I've always been afraid of falling off of bunk beds, ironically enough XD). Speaking of efficient use of space, my friend is renting a teeny weenie room (it's like, half the size of a bedroom in the GH) -- her double bed is a bunk bed, with enough space below to fit a desk and chair. It's ridiculously cramped in there, but still, so cool. *___*
