***Below is an updated picture of my room. We just had new carpet put and I’m going to be looking into a comfy chair which is why you see a kitchen chair in the picture. I would welcome any recommendations on a good listening chair.
What else do you plan to do in the room?
IMO one thing to consider if aesthetics aren't a huge issue is a nice task chair. A good one is extremely comfortable. In the middle of last decade I "test drove" everything out there and ended up finding one called the Contessa by a company called Teknion to be the best fit for me. There are newer ones from the usual suspects (Herman Miller, Knoll, Humanscale, Steelcase, etc.) but I haven't looked into them. (Was going to take my wife task chair shopping last year, but she ended up falling in love with a vintage Emeco secretary's chair at a vintage shop.)
I would strongly recommend against a chair with a large headrest (Eames chaise, etc.), because it will affect both imaging and spectral balance.
