What are important features in a listening chair

I hear you!  https://www.google.com/search?q=live+or+memorex+picture&tbm=isch&hl=en-us&chips=q:live+o...

@dweller - I have not seen this one, that is one special looking chair there! Haha

I had to put my chair up on 4x4s to get my ears at the center of the ESL point source hot spot. 

Good Lord, I have an Ikea Puang and now I have to upgrade that too!?! Work and travel allowing, I listen in the chair 1-3 hours 3-5 times per week, and it is certainly comfy enough to fall asleep in and I like the springiness the frame allows. Is it the head cushion or the materials that make it inferior?  Eames, Erskonne and similar have a "pillow" behind the head like the Puang.  Don't get me wrong, I love these other chairs but my audio $$$ will not be spent this way....yet.

I guess the next obvious question is the need for isolation -
