Stressless w/ ottoman. I've had one of these - Mayfair model - for ten years. Still comfortable. The construction is the same for the entire range of this type. You can spend more if you want fancier features but the parts (springs, chassis, etc.) that make it work and feel good are the same Not cheap but they definitely last.https://www.stressless.com/en
Listening chair
I have seen many threads about equipment but never the listening chair. I tend to like chairs with a low back because I think they sound better. I just picked up a leather ergonomic chair with a hassock. It is the most comfortable chair I have ever sat in and I love it. What do you use?
