My everyday work setup is all ergonomic and good, but sometimes I just gotta get away from my desk. It’s nice to sit on the couch or a comfy chair. But sooner or later (usually sooner) my back and neck start to complain.
Have you discovered any tips to make working in a comfy chair not so hard on your back?
Lean back, not forward.
I work in a hard rocking chair that has this bump on it that hurts my back. Forces me to get up and walk around 
It was built. I couldn’t afford my own piss.
I think its not the chair fault. Every person on job fin its chair uncomfortable at the end of the day.
But if your chair is really not fit for you then change and don’t risk your back on that chair.
