What seat foam density should an executive chair have?

High-quality executive chairs use seat foam with a density rating of 1.8–2.2 lb/ft³ or higher, which maintains support over years of daily use without compression. Lower density foam (under 1.5 lb/ft³) flattens within 12–18 months of heavy use, making the chair feel hard and unsupportive. Foam firmness (ILD rating) is separate from density — ideal is medium-firm (25–35 ILD). Premium executive chairs specify foam density in their documentation.
