I'm a lounger, feet up if at all possible. When I worked at a firm, I excelled, but I "looked" like a lazy-loaf, and I know it's true. I saw pics. I looked like I was being propped up by the desk. But like I said, I excelled. I was even counseled about my "lacking". LOL after almost a year I could do whatever a wanted I wanted without reprisal, but still looked like a bum. I've found comfort is key to productivity, attention, quality and happiness. I'm backing down from $1000 ergo chairs at this point, and considering a combination of sit one way, sit another very different way, stand a little bit, sit reclining, sit normal...blah blah....variation is key.
Gonna try a combo of:
"ergo chair"
"kneeling chair"
"designed for reclining/feet up chair"
"standing"
"standing stool"
