Share details about your chair

Myself is working on a kitchen chair with an extra (very required) pillow on it. The pillow is dirty and should be replaced. That`s why no picture of it. I once got hired by my hero and he had an own office / company with living room furniture. If you worked there, you sat on a living room table with your laptop with four people and a very diverse variaty of kitchen chairs / living room chairs. It was cozy and great. So, now I do it myself as well. I have never physical issues or whatsoever and feel very comfortable but the pillow is needed. Pillow is attached to chair.

I wonder with what for insane chairs you guys come with. Most developers i know have crazy pheripials.
