This posture is called “seiza” (pronounced say’-zah) or kneeling position. Many people think you need a bench to sit in this position, but you can use a zafu to sit seiza, too. If you experience pain in the front of your ankle or top of your foot, in seiza position, try letting them slope down the back of the zabuton as our model demonstrates in this photo.
This second photo shows the “seiza” position using an Omni Bench and a Bench Bag for padding on the seat. People who sit predominantly in seiza position usually use a bench because it gives good support to the lower back.
