Agreed. Definitely wasn't slumped. More like endlessly focused on the task at hand, under deadline. As a tool to keep the mind focused on the work, the Aeron rocked it. Until it didn't because of the back issues.

I have a tendency to forget my body when I focus, which is a plus and minus. It's great for the work, not so great for the body, so having a chair that reminds the body to be active is a plus for the long term.

Personally, I like the combo of a balance board/standing desk. As standing without the board, also caused me to collapse into a leg causing tightness, but with the balance board, I'm always in a slight state of motion, and the muscles are active, so I'm ready to go when it's time to move. As I've aged, I find my focus is actually enhanced as well.
