Good for: 1) taller persons 2) those needing a higher sitting base and 3) those having difficulty sitting in a cross-legged position. The height of this meditation cushion (zafu) helps to bring knees on the mat for comfortable sitting. The double construct lets individuals adjust height by either subtracting or adding filling. For example, the 2 channels can allow for a firm section and an adjustable second section as sitting needs change over time. Particularly good for beginners and those with less flexibility. Ideal for cross-legged or kneeling (seiza) postures. Durable, washable, fabric. Double stitched. Convenient handle. Zipper for adjusting fill if desired.
