-------✧Product Description✧------- This is a set of 2! Large size and high quality!! This is a seat-type posture correction chair. 【Color】Gray 【Extra-Large Plus Version Posture Correction Chair】 With its unique "backrest design that supports with the golden ratio," this new posture correction chair combines beauty and ergonomics! The thickness of the seat and backrest has been doubled compared to the original model. It's comfortable to sit on for long periods, reducing the burden on the lower back and pelvis. It comfortably supports work, study, and relaxation time. 【Achieves an exquisite balance of softness and elasticity】 Using multi-functional polyol elastic cotton material, it achieves an exquisite balance of softness and elasticity that is fluffy yet supportive. 【Industry's largest seat size & 200kg weight capacity】 Adopts the industry's largest extra-wide seat! Size: Length 46 * Width 36 * Height 39cm. Weight: Approximately 2.4Kg. We have achieved a maximum weight capacity of 200kg so that even those with larger builds or those concerned about weight can use it comfortably. This is the perfect chair for those who felt "cramped" or "uncomfortable" with previous models. For office workers, housewives, students, and everyone who has concerns about their lower back. Even during long hours of work in the office, studying, or driving a car, it firmly supports the lower back and back, maintaining a comfortable posture. 【Backrest design that supports with the golden ratio, a fusion of beauty and ergonomics】 This lower back pain support chair is an industry-first innovative design! Based on ergonomics, the height of the backrest module is set to approximately 2/5 of the total height. This is the golden ratio that most stably supports the lumbar vertebrae, effectively reducing the burden on the lower back. It fits firmly on the back and distributes weight evenly. The combination of a natural 'S' curve and a 5° forward tilt angle prevents the pelvis from sinking and the back from rounding, allowing you to maintain the correct posture for a long time. This is an ideal chair that simultaneously achieves posture improvement and comfort for everyone who works, studies, and sits for long hours. 45645593.1000.39
