What are important features in a listening chair

I have 2 of this chair in my listening room, and two small ottomans

Try to avoid some fabrics like microsuede which can cause a static build up when you move to get up from it and then go to touch your gear, it can be hell on your digital in winter. Also I avoid the usual cheap leather substitutes than can creak and fart a lot when you even slightly move around on it, making things a bit noisy.

If there's going to be any creaking and farting going on in my listening room, I prefer it to come just from me.

I am saving pennies for the ultimate chair in the world!!!!!
