A traditional meditation cushion, our round silk zafu has a luxurious, smooth silk cover and 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 finely woven, smooth, high quality silk that is very smooth. 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.
