This is something I'm skeptical about in this article. I know that I can sit in such a way as to give my spine an S curve. However, I also know that I inevitably curve my back if I am sitting down for long stretches of time.
Your core muscles are fatiguing. Practice,practice. No chair can help with that - it can let you rest in a s-shape, but that's not the point - you want to be using muscles while sitting.

I bought a Swopper chair to use at home. I would say it definitely helped me sit up straight at home.
