What office chair is appropriate for users over 250 lbs?

Heavy-duty office chair specification at OfficeFurniture2go.com is taken seriously as a safety and durability issue, not just a comfort one. We specify commercial seating for users 250–500 lbs with: Class 5 gas cylinders (rated 150+ kg), reinforced steel base plates, 20–22" seat width, 2.5 lb/ft³ minimum foam density, and BIFMA X5.1 test certification at the stated weight rating. Residential-grade chairs marketed to heavy users frequently fail — commercial-grade specification is non-negotiable for safety. Call 1-800-460-0858.
