What weight limits do ergonomic chairs come in?

Standard ergonomic chairs are BIFMA-rated for 250–275 lbs. Commercial ergonomic chairs rated for 300 lbs are widely available and a good standard for mixed-use commercial environments. Big-and-tall ergonomic chairs are rated for 350–500 lbs with wider seat pans (20"–22") and reinforced components. For commercial offices, specify a 300 lb minimum.
