Seriously though, my necks hurts all the time now :(

I feel like the ergonomics of this have changed three times in my 30 something years of existence.

That's literally exactly how I'm sitting right now

My legs are down but the back posture is accurate.

I mean, the monitor in the yes pic is outside of the viewing angle! Top of monitor should be aligned eye level.

If only I could understand why I sat the way I did while I was undiagnosed...

So my upper legs need to be squeezed between the chair and the desk? No thanks.

Reject ergonomics, return to goblin.
