What certifications should commercial stacking chairs have?

Commercial stacking chairs should carry ANSI/BIFMA X5.4 certification — the standard specifically for lounge and multi-purpose seating including stacking chairs, covering structural integrity, seat load cycling, back load, stability, and durability tests. The most important tests: a 300–400 lb drop test on the seat; repeated seat and back load cycling (thousands of cycles at rated load); and lateral stability testing. Chairs used in California or buildings requiring fire-code compliance should also meet CAL 133 or CAL 117-2013 upholstery flammability standards.
