Are stacking chairs ergonomic for multi-hour events?

Most stacking chairs are not designed to meet the ergonomic standards of dedicated task chairs for all-day seated work. They are engineered for 1–4 hour sessions. For multi-hour events, look for stacking chairs with: (1) A seat height of 17"–18" so feet rest flat on the floor; (2) A 2"–3" foam seat pad (not less); (3) Lumbar-area contouring in the back panel to support the lower spine; (4) A back height of at least 18"–20" for back support; (5) Armrests (optional but helpful for long sessions). For all-day symposium or conference use, consider providing a stack of padded chairs and explicitly encouraging breaks every 45–60 minutes.
