What does "commercial grade" mean for an office chair?

Commercial grade means the chair meets BIFMA X5.1 standards for commercial office environments — multiple users, all-day use. Key differences from residential chairs include heavier-gauge steel frames, high-density foam maintaining shape after 100,000+ compression cycles, fabrics tested for 50,000–100,000+ double rubs, and 5–10 year warranties.
