Abstract
This item is a chair for maintaining proper posture during zazen, 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 the correct zazen posture with the pelvis upright. The seat is intentionally made shorter in the front-to-back direction, providing stability when seated in the correct posture, while also making it difficult to sit if posture is compromised, naturally encouraging proper posture. The chair is also symmetrical when viewed from the front, and the seat is part of a symmetrical ellipse. This configuration allows the user to naturally maintain the correct zazen posture without any special effort, making it comfortable for everyone from beginners to experts.
