We discussed Tempur-Pedic a bit over in
this thread; I like it a lot. I don't think a larger bed would be of a help; the bed will move either way. You might want to think about moving this forward on your purchase list; you do spend a third of your life in your bed.
Does she realize how much she moves at night? Perhaps you could set up a cam in the room and show her the highlights. Especially if you have sex before sleep that night...
