I have to say that the 'Chain Rocker' is truly badass. Although the chair is not made from motorcycle components, it does actually combines real bicycle parts.
Designed by BRC Designs, the 'Chain Rocker' was constructed out of bike chains and rubber tires. By layering these bicycle elements onto a 98% recycled steel support, they managed to create quite the extreme eco-friendly seat. See this interesting chair for yourselves in the featured gallery.
