An auditorium chair is a chair specifically designed for use in large spaces or public facilities such as auditoriums, cinemas, theaters, conference rooms, and school halls, with the aim of accommodating large numbers of people and providing comfort and durability for large events. These chairs typically have a strong structure with a backrest, seat, armrests, and supporting legs, and are made of quality materials such as steel, plastic, or fabric to ensure long-term durability and user comfort.
