What Is Buckwheat Filling?

Buckwheat filling uses the outer shells of buckwheat seeds. These shells are called buckwheat hulls. They create a firm and supportive meditation cushion. The hulls move slightly as you sit. This allows the cushion to shape around your body. It creates steady support without feeling hard.
Many experienced meditators choose buckwheat because it stays stable. It also helps maintain good posture during longer sessions.
Benefits of Buckwheat Filling
- Provides firm and reliable support.
- Shapes naturally to your body.
- Helps improve sitting posture.
- Allows good airflow through the cushion.
- Stays cool during longer sessions.
- Keeps its shape for a long time.
- Adjustable in many zafu cushions.
- Made from a natural material.
Things to Consider

What Is Kapok Filling?

Kapok comes from the fluffy fibers of the kapok tree. It creates a soft and lightweight meditation cushion.

Many beginners enjoy kapok because it feels comfortable from the first use. People looking for a lighter cushion also choose kapok.
Benefits of Kapok Filling
- Soft and comfortable.
