Wow. We actually like this more than the Jet Set Lounge Chair by Skate Study House.
If you think about it, there are a seemingly endless list of possibilities when it comes to building things with old skateboards -- as long as they are in good shape.The only thing that worries us about these decks from the Roarockit Skateboard School in Toronto is that they look brand new, as though they were produced specifically for the stairs.
Now, if the stairs were made out of skateboard decks that had been tossed aside, that would be truly cool. Either way it's a fun concept and a good-looking way to think about reuse.
