What are important features in a listening chair

My custom made Gilmartin Rocking chair.  Sized to my body and much, much more comfortable then it looks.  Since it was sized to fit me, it offers great back support.  Difficult to get visitors out of the chair once they sit down.  Also looks outrageous. (The chair at the top.)

I've got a shock-absorbing high-speed chair from a SEAL attack boat with a 15" Eminence driver attached under the seat. Bass you can truly feel, but hard on the prostate.

That Gilrmartin Rocking chair is beautiful. It must have cost a small fortune, but to have it tailored to your body makes it worth it. We need more craftsman like that.

All the best,
Nonoise

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

I'm interested in relaxation while listening, so it has always been something akin to or exactly as a stressless design.
