What foam density is appropriate for padded stacking chairs?

Padded stacking chairs used in commercial environments should have seat foam of at least 1.5 lb/cu ft density (comfortable for short to medium sessions) and ideally 1.8–2.0 lb/cu ft for high-traffic venues where the same chairs are used for 4–8 hours per day. Low-density foam (under 1.5 lb/cu ft) compresses quickly under repeated use and begins to 'bottom out' within 1–2 years of heavy commercial use. Back foam is typically 1.5–1.8 lb/cu ft since less body weight is concentrated there. For long-duration events (conferences, lectures), consider chairs with contoured foam and lumbar support built into the back.
