I had a heck of a time at my previous workplace being comfortable; tried different sitting positions, standing part of the day, etc. Then I came to my current workplace which had Aeron chairs. I don't even think about how I'm sitting now, I just sit how I'm comfortable. I sit reclined, my arms only a few inches below my shoulders, resting on my desk. My eyes are level with about 3" from the bottom of my monitors. I'm probably breaking every ergonomics rule. I have to have my phone remind me to get up, if it was just about comfort or back pain I could sit all day. Who knows if there will be long term effects from this, but my body is telling me no. Invest in a good chair.
