What an awesome idea in a little room! Stick a mattress in between and you've saved a whoooooole bunch of waste space. *put some pillows on that top shelf, and you've got a reading nook too! the possibilities are endless!!
Full-sized day bed under windows with book shelves on either side will give her more floor space and lots of storage.
someday when I have an office I want a window seat right next to it. not in any sort of crazy deco like this but the concept is awesome.
