How durable are polypropylene (plastic) stacking chairs in commercial settings?

High-quality commercial-grade polypropylene stacking chairs are more durable in many commercial settings than their lightweight appearance suggests. Commercial polypropylene is UV-stabilized and impact-resistant - a properly specified poly shell chair (glass-fiber reinforced polypropylene is the most robust) handles 10+ years of commercial use without cracking or brittleness. Cheaper injection-molded polypropylene chairs lack the fiber reinforcement and fail faster under repeated heavy use. The frame material (steel or aluminum) is usually the limiting factor rather than the polypropylene shell itself. BIFMA testing is the key quality indicator for polypropylene stacking chairs.
