Factory Direct Partners 18" School Stack Chairs are designed for comfort, durability, and everyday classroom use. Each chair features a molded seat with a vented back for airflow, reinforced ribbing for added strength, and steel lower back support to enhance stability, while the no-snag design keeps screws and hardware fully concealed to prevent catching on clothing or hair. With a 18" seat height, these chairs are appropriately sized for ages 12+, making them ideal for middle school and high school classrooms, libraries, and recreation centers. Non-marring swivel glides protect floors and move smoothly across both hard surfaces and carpet. Chairs arrive fully assembled and stack up to six high for efficient storage, making it easy to quickly clear space for group activities. The surface is easy to clean and sanitize; simply dry chrome and glides after cleaning to maintain finish quality. GREENGUARD Gold Certified for low chemical emissions and meets ANSI/BIFMA X6.1 standards for educational seating, addressing safety, durability, and structural integrity.
