Once again the chair is nothing special but I have found it to be quite comfortable. It is a good chair for under $200. Here is the Amazon link https://www.amazon.com/Serta-Health-Wellness-Executive-Office/dp/B00EUU5G82/ref=sr_1_1?ie=UTF8&qid=1496667176&sr=8-1&keywords=serta+air+health+and+wellness+executive+office+chair
I think it is definitely worth the splurge on a nice chair, but I think under $200 is reasonable and gets you a lot of good options. Personally, I bought https://www.amazon.com/Serta-Health-Wellness-Executive-Office/dp/B00EUU5G82/ref=sr_1_3?ie=UTF8&qid=1537827716&sr=8-3&keywords=serta+computer+chair, which I love

I just looked for sales on Amazon. The problem is that prices can vary a lot (and spending a lot doesn't mean you get a great chair).
I bought this one in 2017, but I spent only $120 on it, not the $220 it is now. I love it, but wouldn't have spent twice as much on it.

If you happen to live near an office supply place (if retail still exists), they usually have floor models you can try out. Otherwise, I just watch Amazon for sales (again obviously prices really vary) and look for something that looks good. Ordering online unfortunately involves taking a little leap of faith as you can't try it out.
It doesn't hurt to throw in a little support for the backside as well. I cracked a tailbone when I was younger (a real pain in the a**!) so one of these are cheap and really make those longer sessions more comfortable.
