Designer Alejandro Aravena of the firm Vitra created a very simple chair. It's a strap that wraps around your legs and back to hold you into a seated position. "Chairless" was inspired by a picture of an Ayoreo (an indigenous group in Paraguay) person doing something similar. A portion of the proceeds from this chair will be donated to a foundation to benefit indigenous nations of Paraguay.
