Dumb question? WHAT IS YOUR SEAT/ CHAIR?

I would be worrying about the reflections of the chairs "wings" first then the lack of the side and back wall reflections for ambience. I think the "wings" are going to make the sound seem to beam from the speakers accentuating the highs and the mids to a lesser degree. Beautiful chair for reading but not for audio!!!
I have an Ekornes Stressless "Savannah" with Tigereye Royalin Leather. The headrest comes to just above my ears producing a slight reflection, I unzip and remove it then my ears are above the chair back which I prefer for listening but not TV!!!

i used to use eames chairs but they are uncomfortable and too expensive.. great to look at tho. now i use ikea chairs. much better value

The seating seems to make a very large difference.

I orignally was using a chair from Plummer's (a cheaper knockoff of the Ekornes style), but I found that some of the internal springs buzzed during loud bass passages. Then I moved to a leather sofa with the back around mid-ear level. I used a thin blanket over the back and found it helped cut out some excessive sibillance. I recently tried a thick comforter, and it helped further. I then moved the sofa off to the side of the room and tried a cloth office chair (the back was well below ear level)--- and WOW! what an improvement on the clarity of the treble! This won't be my long-term chair, but now I am looking for a chair or sofa with a low back, made of cloth with some decent padding. My cable dealer heard the story and thought there had been comb filtering going on.

Ekornes or similar;I have both.

Ikea Poang chair. Very comfortable and supportive. The back is a little higher than my ears. It puts my ear height at about 34".
