Why the cutout
In cross-legged sitting the thighs need to angle downward from the hips toward the knees. When the hips are not yet open, the femurs can't rotate enough for the knees to drop below the pelvis on a round cushion — they catch on the front edge, the lower back rounds, the spine collapses, the practice gets harder than it needs to be. The crescent cutout removes the front edge entirely. The thighs drop through the gap; the knees find the floor; the spine stacks cleanly. The cushion gets out of the way.
Same height as the Round Zafu
The seat height is 9.5 inches — the same as the Round Zafu and Meditation Cushion. The crescent does not reduce the lift; it changes only the front profile. If you have used a Round Zafu and felt the hip flexor strain of forcing the thighs forward, the Crescent gives the same elevation without the strain.
Kapok, briefly
Kapok is a tree fibre — light, silent, and resistant to mould. The crescent shape uses the same dense fill as the Round Zafu — firm under the seat rather than soft — and holds the curved shape across years of use.
Care over the long run
Cover removes via the hidden zip — machine wash cold, hang dry away from direct sunlight. The kapok inner pillow does not need washing; vacuum lightly if dust builds up. The cushion holds its crescent shape for years; the cover softens with each wash.
