You have options. If a king, get a firmer bed you like and she can place a twin XL plush topper on her side. Or you can get a split King and you can each get separate twin XL mattresses for a little more $$. A bed bridge placed beneath mattress protector and fitted sheets help camouflage any dip in the middle. Want to get fancy? Do this with an adjustable (split king) base. Not difficult.

Does anyone know of a memory foam mattress that is only firm on one half?
The local natural bed place I got my latex from does half and halfs. I wasn't impressed with the sleep number. It doesn't so much soften as sag when you deflate it. The middle of the bed, between the airbags, is noticeable. More on reddit.com
