We have been thinking, what kind of chair is a good chair? How to evaluate a chair more scientifically and effectively? To this end, we have collaborated with associations and industry experts to establish the Xihao Ergonomics Research Institute, Laboratory Testing Center, and R&D Center dedicated to developing new sitting sensation technologies. Through research and testing on the interaction between human sitting capacity and seats, as well as their impact on human perception, we evaluate and improve the comfort, support, and ergonomic performance of seats using scientific methods and objective indicators to guide seat design, improvement, and optimization, and provide better sitting experience and health protection.
