Since your room is a childs room, you might want to consider drawers and/or
cabinets UNDER the bed. Beds take up most of the space in a room, so why
not make use of that space. Depending on how high you make the bed, you
could store a lot in that area. I've seen ready to assemble systems that
include small closets and even a desk under the bed.


SOmething like this?
