I'll be the dissenting vote for those Kijaro chairs. My in-laws have them and so do friends and I just don't find them to be very comfortable. I've tried 2 different ones of them. They're a world better than the cheap folding chairs, but still aren't my cup of tea.
I've wanted to try a Strongback Chair for a while, but have a super hard time justifying the $100 price tag. https://www.strongbackchair.com/
Our most recent chairs are the Comfortsmart Chairs from Coleman:
Coleman - comfortable camping chair - coleman camp
I like these better than any other chair. The downside is that they don't fold down very small.
My true favorite is a campchair that Sams Club sold 15-20 years ago. They were sturdy and well made. Unfortunately, I can't find them anywhere any more. If I did, I'm betting I'd buy enough to fill a basement and would just swap them out every 10 years.
