What are Zafus?
"za'foo: an oval shaped cushion used for everyday sitting in Asia for centuries. Today the zafu is rediscovered by Westerners for meditation, yoga, and simple home furnishing." The zafu often thought of as only a yoga cushion or meditation cushion, has many other uses. It is a perfect bolster for stretching the back, and converts almost any chair into a tilt seat for autonomous sitting.
