Zabutons are a large flat mat dsesigned to go underneath
your meditation bench or cushion to make your meditation experience
more comfortable. It is a wonderful way to help relieve pressure on
your knees, ankles or feet while you meditate. With a zabuton, many
people find that they can meditate far longer before needing to get
up or shift their position.
Zafus are a round cushion for sitting meditation and
traditionally goes on top of a Zabuton. The cushion raises the
hips, making the entire range of cross-legged sitting positions
more stable for the meditator.
In western terms, colloquially speaking, zafu refers to a
meditation cushion, and zabuton refers to the large cushioned mat
on which a zafu is placed.
