The zen pillow is similar to a traditional zafu. The rectangular shape makes this a versatile yoga prop, useful for meditation, sitting, and as a bolster for reclining poses. Each zen pillow has a sturdy handle sewn on one end. We offer our zen pillows with  Buckwheat hulls. The filling is densely packed to provide a solid cushion, and yet is soft enough to be comfortable. The outer cover is made of 100% American twill cotton. The zen pillows have a zippered opening, so the cover can be removed for washing. You can also adjust the amount of stuffing in each zen pillow, thus changing the height and the firmness. Each zen pillow is 15" long, 11" wide, and 5" tall. Up to 6 lbs. in weight and is available in 5 of colors.
