Functional stairs, saving space

I thought of this before...never patent it...damn..im lazy

I would totally buy this!

With my luck, i would probably fall on the stairs

What if you fell down the stairs. Those metal pully things aren't very convenient

Imagine walking down the stairs and tripping over a not-properly closed drawer;... And triping, falling... Imagine all the crunching of Bones and the bruises, and sprained ankles...

I sure hope there's only one person living there...
