Yoga-Mad's crescent-shaped zafu cushions fulfil the same purpose as a traditional round zafu, though the crescent shape provides more support for your upper thighs, which some find more comfortable. Being approximately two thirds the size of around zafu also makes it relatively lighter and more convenient to store and transport. Our crescent zafu slopes from 7.5 at the back to 4.5 at the front which ensures you pelvis remains above your knees, which is essential for comfort. The cushion is pleated for extra durability and is filled with natural buckwheat hulls which conform to your body shape perfectly whilst providing a stable platform to sit on. The cushion comes with a handle for easy carrying and a hidden zip allows you to add or remove buckwheat hulls to adjust the loft to suit you. Use a Zabuton with the Zafu to provide a cushion for your knees and ankles. Features Crescent Shaped Zafu Cushion 100% cotton drill cover with zip access to allow topping up.
