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.

Hi, I'm trying to find a decent small chair or stool for backpacking, that will support a big dude. REI and others have some ultralight stuff that goes up to 250-275 but I weight in at 275. On the other end are larger camp chairs that will support 400lb.

Any luck for the big dudes out there? I'm sure most of the long haul market is made for wireyabd compact folk.

Im looking for a nice camping chair. Something comfortable that I won't sink down into.
