What weight capacities do ergonomic chairs come in?

Standard ergonomic chairs are BIFMA-rated for 250–275 lbs, but commercial-grade chairs rated for 300 lbs are widely available and a better baseline for mixed-use office environments. Big-and-tall models jump to 350–500 lbs with reinforced frames and wider seat pans (20"–22") built to match. If you're outfitting an office with diverse users, 300 lbs minimum is the smart spec.
