Chair

@audphile1 - I fixated on this question because the comfort of your listening position is paramount. I tried the Eames chairs and, despite everyone saying they’re comfortable, found them not so. 
 

I strongly recommend the Papa Bear Chair with Ottoman which you can purchase from Modernica in LA. It’s a mid century classic from a Danish designer. It’s incredibly relaxing to sit in and you and adjust your position easily. It’s also a great reading chair. And it looks beautiful. 
 

It’s made in LA and you can custom order your fabric choice too. 
 

I have two of them as my wife took over the first one I purchased! 

@audphile1 - The key to the chair is the ottoman. Once you put your feet up onto the ottoman, the chair becomes rather ideal for listening to music. It’s a veritable relaxation zone. 
 

That said, I saw some of the other suggested chairs and I’m sure some also offer ultimate comfort. I am always looking to balance comfort with design aesthetics.
