How does seat foam density affect office chair comfort and longevity?

Foam density specification at OfficeFurniture2go.com is disclosed on every commercial chair we sell — 1.8 lb/cu.ft minimum for standard commercial use, 2.2 lb/cu.ft for premium chairs, and 2.5+ lb/cu.ft for multi-shift and high-weight applications. We do not sell chairs with foam below 1.6 lb/cu.ft for commercial applications. Foam density is often the hidden variable behind 'this chair was great for a year and now it's terrible' complaints — the foam has compressed permanently. Specify density, not just price.
