What are important features in a listening chair

I'm interested in relaxation while listening, so it has always been something akin to or exactly as a stressless design.

This is the chair I use. To me it's the ideal listening chair. It's a bit pricey, but goes on sale a few times a year.

I look for 3 things.
1. Comfort
2. Comfort
3. COMFORT
I like the Erkornes chairs myself. 

A person listening!

For proper back support, comfort, durability, looks and angle adjustability, it is hard to beat Ekornes Stressless chairs. Yes, they are fairly expensive new, but you can find some nice ones on the used market between $500-$700. As comfortable as it is, I don't tend to fall asleep on it like I do some of the other recliners I have had in the past. I can't even begin to count the number of times I've sat down, looking forward to listening to an album, only to wake up 3 hours later and discover that I slept through every track and two hours beyond that!
