What kind of listening chair

As with most things, it is good to sit in a chair before buying.  The Eames chair appears to have a headrest, but it is not.

"The Eames lounge chair doesn't have a headrest. It looks like it does due to the fact that it's rarely photographed in such a way as to figure out scale. The top of the chair back is 32" from the floor. For reference the average upholstered chair has a back height of 32 - 35".

a nice firm couch with no sag to it, and solid back and thigh support. 

One that gives me good back/lumbar support, like the zero-gravity chair I use for listening, television, reading, etc etc....

You\r chair people need to buy my, natural, organic, rubber coasters to isolate the chair from the floor.  I have two models, one for turntables, and one for CD's  We are working on a streaming one.  When ordering for a turntable, please specify whether you use a moving coil or magnetic cartridge, as well as whether the latter is moving iron or moving magnet.  I have my ears above my chair back, but I also have half of my house open behind me.

I put my speakers on the ground. That way, I don't need a chair. I bought a lot of extra music with the money I saved on both speaker stands and a chair. According to Stereophile, you should have more money invested in the music collection than in the kit.
This is what staying home because of COVID does to a person.
