What are important features in a listening chair


Been wondering what features are important to you in a listening chair. 

(Besides the drink holder and familiar smell...)

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?
My ideal chair is what you would find in a dentist office. Has the headrest that covers the back of your skull and that's about it. A built-in motor to vibrate with bass frequencies (without the sound) for apartment-dwellers would be nice. Cover mine with alligator, please...

yes, but more so that the sound does not reflect from the back of the chair directly into my ears. Also, I want to hear the back wall reflections to give a realistic audible impression of my visual surroundings. I like the audio-visual environment to be integrated. Otherwise, I might as well just use headphones.
The IKEA Puang Chair takes a lot of heat from yours truly due to the foam they use in the chair. It’s a Trojan Horse. It might be the worst thing ever foisted on gullible naive audiophiles. Makes the sound all weird and phasey like. Very reminiscent of SONEX, another sonic catastrophe.
