What is a conference chair seat cushion density?

Commercial conference chair seat cushions use medium-density polyurethane foam rated at 1.8–2.5 lbs. per cubic foot (density) with an ILD (Indentation Load Deflection) of 40–60 lbs. Higher density (2.5 lbs.+) and higher ILD (50+ lbs.) foams resist compression over time, maintaining comfort even after years of use.
