T-Shirt Chair

This T-shirt Chair by Maria Westerberg recently won the 2011 Green Furniture Award.

You can order it as an empty frame, where you then collect 40 used t-shirts and weave them into the frame for a soft and colorful chair.  (It's also available pre-made, using sofa manufacturing scraps.)

Unfortunately, I can't find it for purchase yet in the U.S.
