A chair is a piece of everyday seating with a backrest and armrests. Its history can be traced back to the aristocratic chairs of the New Kingdom of ancient Egypt. The earliest image of a chair in China is found in the rope bed depicted in the murals of Cave 285 at the Mogao Grottoes of the Western Wei Dynasty. The term "chair" appeared in the Tang Dynasty, and basic forms such as the folding chair and the grand master's chair emerged in the Song Dynasty. Ming-style furniture became a world standard during the Ming and Qing Dynasties.
Traditional chairs served as symbols of status, such as the royal throne ceremony of Louis XIV and the dignified tradition of the Chinese grand master's chair. Modern chairs incorporate anatomical design. In the 18th century, the French physician Nicolas André de Bois-le-Garde first studied the relationship between the human skeleton and chairs. Contemporary chairs have developed into ergonomic chair categories, utilizing smart chips and high-sensitivity sensors to achieve dynamic lumbar support, integrating immersive acoustic systems and health monitoring functions. In 2025, the industry introduced three-zone adaptive lumbar support technology and high-elasticity, anti-attenuation mesh fabric.
