This is a set of one Zafu and one Zabuton meditation cushion with non-removable 100% cotton twill fabric covering. The round Zafu meditation cushion is filled with your choice of Kapok, (a dense, cotton-like substance) or Buckwheat Hulls (small grain-like hulls). The Kapok is firm yet shapeable. The Buckwheat Hulls easily conform to the shape of your body and offer a grounded feeling. The Buckwheat Hull Zafu has a zippered opening that allows you to adjust the level of hulls to your comfort. The Kapok Zafu has a compression opening to release air, but it is not recommended that you remove any kapok fill. The Zabuton is filled with a 3″ thick layer of cotton batting that is tufted in five places to prevent movement and bunching up of the batting. Both Cushions are Economy versions with non-removable covers. Together, the traditional Zafu and Zabuton create a comfortable sitting place for meditation and are popular with meditators all over the world. These high-quality sets are available at a significant savings over purchasing the cushions separately. Please note that the actual fabric color may vary from the image representations.
