The thickness of the seat and backrest has been doubled compared to the first generation. It's less tiring even when sitting for long periods, reducing the burden on the lower back and pelvis. 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 firmly 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 "difficult to sit in" with conventional models. For office workers, housewives, students, and everyone who has lower back concerns. Even during long hours of work in the office, studying, or driving a car, it firmly supports the lower back and back, keeping 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. 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. An ideal chair that simultaneously achieves posture improvement and comfort for everyone who works, studies, and sits for long hours. This is a must-try item for those who suffer from lower back pain and hunchback.
