Abstract
This item is a chair for maintaining proper zazen posture, a piece of wooden furniture made from solid cedar. It is particularly designed with a guide that supports the sacrum, allowing the user to naturally maintain proper zazen posture with the pelvis upright. The seat is intentionally designed to be short in the front-to-back direction, providing stability when seated in the correct posture while making it difficult to sit if posture is compromised, naturally promoting proper posture. The chair is also symmetrical when viewed from the front, and the seat is part of a symmetrical ellipse. This design allows the user to naturally maintain the correct zazen posture without any special effort, making it comfortable for both beginners and experienced zazen practitioners.
