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.
Hammock bed - this gave me an idea. wouldnt it be fun (if i was rich) to have a huge kids playroom with a built in indoor trampoline for the kids to jump! (kinda like where this hammock is- floor level- but tramp! I want this one day :)
