Are there heavy-duty executive chairs for larger users?

Yes. Big and tall executive chairs are specifically engineered for users up to 400 lbs or more, with reinforced frames, wider seats (23"–26"), extended seat height ranges, heavy-duty gas cylinders, and wider armrest spacing. Standard executive chairs typically support up to 250–300 lbs. Placing a large user in a standard-rated chair creates safety and durability risks.
