The ones you link are absolute garbage that buy their rating. They will go flat in about a year. If you invest more you can get a chair for basically life.

All are top brands, stupid expensive new, worth, but stupid expensive. My advice is to go to office resellers. They have some in pretty much every city. You can find killer stuff even if it’s not the best brand. But most are actually quality. All at about a third of the cost you’d be paying new. Which sort of ends up about the same, or a bit cheaper than Amazon crap.
