What foam density should commercial lounge seating have?

Commercial lounge seating should use foam rated at a minimum of 1.8 lb/cu ft density with an ILD (Indentation Load Deflection) of 35–45 — firm enough to maintain support over years of use without bottoming out. High-end models use 2.0–2.5 lb/cu ft foam. Residential furniture often uses 1.2–1.5 lb/cu ft foam that breaks down within 1–2 years of commercial use. At OfficeFurniture2go.com, our commercial lounge seating uses foam rated for 8+ hours of daily use — call 1-800-460-0858 to confirm specs on a specific model.
