What seat pan material is most durable in a conference chair?

The seat pan in a conference chair consists of a structural shell (typically injection-molded polypropylene or pressed steel) topped with foam and upholstery. Polypropylene shells are lighter but can crack under extreme weight or lateral stress. Pressed steel shells are heavier but virtually indestructible. The outer upholstery (fabric, vinyl, or mesh) takes the most visible wear. For maximum durability, choose chairs with steel or high-density polypropylene seat pans and commercial-grade upholstery rated for 200,000+ double rubs.
