A small space idea, like a tree house in your room. Utilize all space with shelf stairs up to the bed box. Get a closet too and all of it up off the floor space. Great for a boys room. Put a BB Net on the bed and voila! they can play indoors.
A cool idea on using the space of the corner cabinet ! With these shelves, you can organize, see what's in it and not have to get down on your hands and knees if there was a lazy Susan in the space. Down side--- no hide and seek space.
