What are important features in a listening chair

Thanks.

I gather so the back of the chair does not effect sound as it moves through the room? 

Do you have any pref. re: materials used and/or adjustability?

I use a Herman Miller office chair at the moment, with a low back, but I feel like I'm in a classroom listening to my teacher... To make it even more comfortable, I have had to add a cutting board on top of the cushion to help with my sciatica. So, I've been wanting something more comfortable. @geoffkait  Agree re: Puang, considered it for a brief second, but then realized I would be basically putting a pillow behind my head, and thats no good... 

@dweller Would really like some head/neck support also as I have a bad neck and lower back - thank you reckless youth - but don't want to have the headrest part interfering to the sound as per @whostolethebatmobile.

Am thinking of something with a light mesh, but curious if that will cause any diffraction of the sound or if it would work more like a speaker grill cloth and be "mostly" transparent.

@dweller How were you misunderstood?
@larryi Wonder if there is a chair specifically deigned to "focus" the sound? Like a satellite dish...
@ivan_nosnibor I guess you listen alone :)
@elizabeth It be good speak listen

Wonder how using acoustic wool as a "stuffing" material can help with the chair being acoustically inert.
