What foam density should I look for in upholstered stacking chairs?

Upholstered stacking chair seats and backs should use foam of at least 1.5-1.8 lb/cu ft density for commercial use. Budget stacking chairs often use very low-density foam (under 1.2 lb/cu ft) that compresses and flattens within 6-12 months of regular use. High-quality commercial stacking chairs use 1.8-2.0 lb/cu ft foam that maintains its shape through years of daily use. Slab foam (one piece) is simpler; profile-cut or contoured foam better supports the human body. For comfort-focused event venues or long-session training rooms, the foam quality is worth the premium price difference. FindOfficeFurniture.com - 888-719-4960.
