I love, love, love the shoe cabinets! They take up so little space and hold EVERYTHING from shoes to sheets to rolled up towels. I used the black Trones shoe cabinets in my last bath for towel storage that only took up of space.
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.
