Please see my profile before purchasing (*'ω'*) I have many other items for sale (^o^)/ #various★shop ★【Brand new, unused】 so please rest assured ♡ 【Two evolution points! ① Bird wing design ② Improved cleanliness】 ① "New backrest design like a bird's wing" In conventional models, some people felt that the backrest was a little hard or that the support was insufficient. Therefore, in the 2025 model, we changed the design of the backrest to a shape like a bird's wing. This design provides firm back support and maintains a natural posture, providing the wonderful effect of making it less tiring to sit for long periods of time. 【You'll want to sit in it forever! Impressive comfort】 To achieve both comfort and posture improvement, we conducted hundreds and thousands of tests, considering various body types and sitting styles, and found the optimal firmness. A cushion has been completed that provides "the ultimate sitting comfort" with a balance of just the right firmness and softness, reducing fatigue even after sitting for long periods, naturally correcting posture during desk work or driving, and preventing lower back pain. We are particular about the materials of the cushion, and while maintaining adequate support, it is comfortable to sit on, reducing the burden on the lower back and allowing you to maintain correct posture. 【Lightweight and highly portable! Can be used anywhere】 This "Posture Support Chair" is also highly attractive for 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 all kinds of situations. In addition, during long commutes, business trips, and travel, this posture support chair provides a comfortable sitting experience like your own chair, even in car or train seats. Furthermore, while being lightweight, it provides firm lower back support, effectively correcting posture and reducing the burden on the lower back in any location. Especially for those who spend a lot of time sitting, such as at a desk in the office or while driving a car, this cushion is an essential item.
