Graypants debuted the Slice Cafe + Dining Chairs at ICFF this year. Three chairs can be made from one sheet of plywood, and the only waste created is sawdust. The chair is finished with low-VOC coat that is a byproduct of cheese.
While I saw several products like this at ICFF, I appreciate that Graypants' commitment to sustainable production extends to their whole collection. For their Scrap light fixtures, they apparently hire homeless folks in Seattle to collect cardboard, which they then laser cut to create the light fixture.
