KOJIHOMU posture correction chair was developed over five years by experts who researched the physical characteristics of Japanese people, and it was designed with the aim of "maintaining correct posture," "reducing the burden on the lower back," and "achieving a high-quality sitting experience." Sitting in this chair instantly allows you to sit correctly, as if you were being taught by a professional instructor, straightening your back and relaxing your spine. You can be freed from slouching and unnatural sitting positions, regain a healthy posture, and reduce fatigue while protecting your lower back. You no longer have to worry about bad posture. ① "New backrest design like a bird's wing" In previous models, we received feedback that the backrest was a little hard or that the support was insufficient. Therefore, in this 2025 model, we changed the design of the backrest to a shape like a bird's wing. This design provides firm support for the back and maintains a natural posture, while also providing the wonderful effect of making it less tiring to sit for long periods of time. It fits the body better and provides a comfortable sitting experience. ② "Removable cover" In previous models, cleaning was a little troublesome when it got dirty, but in the 2025 version, the cover is removable and can be easily washed at any time. ◯ We are particular about the material of the cushion, and it provides a comfortable sitting experience while maintaining adequate support, reducing the burden on the lower back and allowing you to maintain correct posture. This cushion also considers breathability and is designed to be comfortable to use even in hot seasons. ◯ This "posture support chair" also has great appeal in its lightness and portability. Compared to conventional floor chairs, it is surprisingly lightweight and easy to carry. You can easily carry it anywhere and it is useful in any situation. Furthermore, while being lightweight, it provides firm lower back support, so it effectively corrects posture and reduces the burden on the lower back in any place. ◯ It has been opened for photography, but it is brand new and unused ✨
