How about
: A make-up themed bed? It could be like an open compact and the pillow could be the little pad you put makeup on with.
A book bed for book enthusiasts.
A rocket ship bed.
A flower pot bed.
A coffee cup bed.
A world bed (globe cut in half look?).
A porcupine bed (of course the needles would be soft!).
A cloud bed.
A lamb bed.
A heart bed.
A swan bed. (The body would be the bed, and it would have a swan neck)
A lily pad bed.
A water lily bed.
Umm ... okay. I ran out of ideas.
