What is the opinion of Reddit about the
Flash Furniture HERCULES Series 24/7 Intensive Use 300 lb. Rated Black LeatherSoft Multifunction Ergonomic Office Chair with Seat Slider?

I’ve heard the Hercules series or 24/7 intensive use series chairs from Flash Furniture are good and they’re not ridiculously expensive. I just ordered this one https://www.amazon.com/dp/B01KA7WXKW/ref=cm_sw_r_cp_awdb_QDcwzb9DQQWPF. It’s was a Amazon warehouse deal (returned item) for $120 so I’m hoping it’ll be good.
I’ve been using a $100 chair from Staples for almost 3 years and it’s not even that bad just not comfortable for long sessions.
