Artist Nick DeMarco from California College of the Arts designed this chair for a sustainable production furniture class. His XS chair is essentially a shell that can be filled with any excessive item you have around the house — from bottles and cans to old clothes or newspapers. He wanted to draw attention to the reality of trash, and how it can be reused. The chair was presented at the ICFF in New York this month, as part of the Sustainable Design For Mass Production exhibit. While I think the project works on a conceptual level, I can't imagine even the most eco-hippie communal homes filling their living room with such furniture.
