What seat foam density should an ergonomic chair have?

Commercial-grade ergonomic chair seat foam should have a density of 1.8–2.5 lbs per cubic foot (PCF). Foam at this density maintains shape and support through 100,000+ compression cycles. Foam below 1.5 PCF compresses and loses meaningful support within 2–3 years of daily use — a common complaint with entry-level chairs. When foam density is not disclosed in product specs, treat this as a warning indicator of lower material quality.
