How wide is the seat, and how much weight does the chair hold?

One figure in this group is published, and it belongs to the plain Heavy-Duty chair: a steel frame rated to hold up to 500 lb, under an oversized seat and back and between two cup holders big enough for a travel mug. That is the chair to choose when you want room rather than the lightest thing in the trunk. The other two are built for ordinary adult use, but their suppliers do not publish a capacity, and we would rather tell you that than repeat a number we cannot stand behind - if the figure matters for a specific chair, send us the model name and we will confirm it with the supplier before you order. All three fold square in the usual quad-chair way, which makes them easy to stand in a corner of the garage, and the Heavy-Duty and the Deluxe Heated list a carry bag in the box.
