Zafu? This video will help you answer the question "Is the Zafu cushion right for me?" This short video includes a discussion of both the shape - traditional round or our Half-Moon (crescent-shaped) Zafu - as well as the choice of fill - the softer but resilient Kapok Zafu or the firmer but "moldable" Buckwheat Zafu. Note: the Kapok Zafu is our most popular and is available in a Deluxe Zafu version which comes with a washable zippered cover. The Zafu Support Cushion goes under the Zafu to add height. The video also shows the Zabuton, the mat cushioning the knees and ankles.
