How thick should the seat cushion be on a commercial stacking chair?

For commercial stacking chairs, seat cushion thickness should be a minimum of 2" for comfortable short-to-medium duration seating (1–2 hours) and 2.5"–3" for longer events (2–4 hours). Thicker cushions (3"+) are preferred for all-day conference or training room use. The cushion thickness visible in product photos can be misleading — verify the actual foam thickness in the product specification sheet rather than relying on visual estimation. Foam density is equally important: 1.8 lb/cu ft minimum for commercial use. A thick but low-density cushion will compress quickly; a thin but high-density cushion will last longer but feel firmer.
