What types of cushion fill are used in commercial lounge sofas?

Commercial lounge sofas use several cushion constructions: high-density foam (the most common commercial standard — firm, resilient, won't compress quickly); foam wrapped in Dacron (polyester batting around the foam for a softer, tailored appearance); spring-over-foam (sinuous springs under foam for more resilience and longevity); down/feather wraps (luxury tier — soft and lofty but requires more fluffing and is harder to clean). For commercial applications, high-density foam (at least 1.8 lb/cu ft for seats, 2.0+ preferred for heavy-use pieces) is the most practical — it maintains shape, cleans easily, and doesn't require maintenance.
