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. FindOfficeFurniture.com sources ergonomic chairs with commercial-grade foam density — call 888-719-4960.
