I am trying to find suggestions for a folding stool or chair with no arms (the sides often cut into the person's legs), that have a decent sized seat to fit a large bottom, and can hold at least 450lbs. or more. We are trying to go camping and the person uses a walker and often needs to sit while walking on trails, so having a folding stool/chair like this would help them be able to participate with everyone still. It doesn't necessarily have to be a camping item as long as it fits the needs listed above. Any help with suggestions for this would be greatly appreciated!
Edit: I forgot to note that this is for California, USA for access to buying location-wise.

Final Edit: Thank you all for your suggestions. We decided camping love seat is the way to go. A friend had one and they tested it out and it works well.

I looked in the sub and didn’t see anything about this. Does anyone have a packable stool or something?

I am also interested in a folding bike (not expecting that to fit in my bag!) but if anyone here has traveled with a folding bike i’d love to hear your experience!
