What is your listening chair?

Isn't it best to have a chair that does not come up as high as your head? Otherwise, would it be like sitting with your back right against a wall?

Mine is a common low back task chair on wheels with no arms that is height adjustable via a pneumatic base. It allows me to move my listening position slightly as may be needed. Unfortunately, the pneumatic base is leaking and I get shorter and shorter as the listening session goes on. Very annoying!
That's why I am visiting this thread looking for ideas for a replacement.
