Have you considered Herman Miller and Steelcase Leap V2 (Youtube review and comparison?) These two are popular but rather expansive.
I got a refurbished Leap V2 cheap (~$220) from local secondhand office furniture store.
I specifically looked for these secondhand office furniture stores, they often acquire large amount of high end office chairs from closed businesses. Since the chairs are coming from conference rooms, they are usually in good conditions and I can worry less about indirectly touching someone else’s ass or genital.
Just trying to be helpful. I understand that used furniture may not be acceptable to everyone.
I thought the Herman Miller and Steelcase Leap V2 are worth mentioning because they represent the medium-high end products in the “ergonomic chairs” market, which gave me an overall idea of what features to expect in a good chair.
But all of that are just talking theories, I think the most important thing in picking a long-term chair is to try it out in person first to make sure you like it.
When I was doing my chair research 2 years ago, I heard good things about IKEA “markus” chairs which fits your price range. If you don’t like your current order, you may also consider checking that out.
I can tell by reading customer reviews if a chair is something that I might like, but trying it out in person would be a nice option to have after I read the reviews.
By the way, although I like the padded armrests in the OP, I can live with other types of armrests if they are done right, and I can get pads for hard plastic armrests.
I read a lot of customer reviews on Amazon for gaming chairs, and I read a lot of horror stories, so I'm very glad that so far I can live with this chair.
