A traditional meditation cushion, our zafu is a crescent-shaped cushion with pleated sides. Each zafu has a sturdy handle sewn tightly on one side. These zafus are filled with organic buckwheat hulls. The buckwheat hulls provide a firm cushioning, and can be added to or removed, to adjust the cushioning, through a small side zipper. The outer cover is made of a sturdy, 100% twill cotton. The zafus have a smaller zippered opening, neatly hidden between pleats, that can be used to remove the cover and wash it. Each zafu is 15" in diameter and 6" in height, and is available in a variety of colors. Zafus are typically used with a zabuton cushion to provide comfort and support to assist you in your sitting practice.
