What are important features in a listening chair

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...

Totally misunderstood (as usual).

@dsotm073 - Have you seen the "Pelican Chair"? Looks like it blocks side-wall reflections before they reach you! 

Little known secret: Sitting in a IKEA Poang Chair, wearing an Urban Sombrero (from Seinfeld show) tilted at precisely 45 degrees, almost replicates exactly the acoustics of Carnegie Hall!
