What are important features in a listening chair

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.

Totally misunderstood (as usual).

I have a large leather arm chair with ottoman. I'd say that for me comfort is the number one priority. No matter what a chair means to the acoustic equation if it isn't pleasant to sit in then its useless.

It has a high back, but I am tall. I can sit with my head fully above the back or slumped down so that the back is higher than my head. There is no sonic difference whatsoever.

Low-back chairs will reduce reflections from the chair itself affecting the sound.  That, at least in theory, makes them preferable to chairs with headrests that stick out to the side.  But, in practice, I don't mind the sound when sitting in a comfortable chair with a high-back headrest.  The sound seems well focused when I sit in these types of chairs.

I have 2 of this chair in my listening room, and two small ottomans
