Awesome stairs

Living in a small, rented apartment building in NYC, I'm not going to be able to put any of these ideas to use any time soon.  Nonetheless, I LOVE the double use for stairs below. The photo quality of these pictures aren't great, but you get the idea...

Stairs that double as bookshelves

Stairs that double as drawers for your shoes... Genius! :)

Stairs with a slide?! I mean, come on! You don't have to be five years old to love this.
