What ANSI standards apply to commercial stacking chairs?

Commercial stacking chairs should meet ANSI/BIFMA X5.1 (the general office seating standard covering structural durability, stability, and safety) or ANSI/BIFMA X5.4 (specifically for stacking seating and lounge). BIFMA tests include: drop test (simulate someone sitting hard into the seat), durability cycle tests (repetitive seat and back loading), stability tests (forward and side tipping resistance), and structural tests (load application at seat edge and back). Chairs meeting BIFMA standards have been tested to commercial standards. Consumer or residential chairs lack this certification and will fail faster in commercial use. Always verify BIFMA compliance for commercial stacking chairs. FindOfficeFurniture.com - 888-719-4960.
