1) Main is a standing desk with a wobble board. The wobble board allows for constant micro-adjustments and also a few good 'steady' position for focusing

2) Ikea Nilserik wobble stool. This lets me "perch" in a semi standing position and, again, make lots of movement throughout the day. I also reposition myself on this regularly.

3) Kneeling chair

4) normal office chair for little breaks (30 minutes in the morning and 30 in the afternoon)

I would never go back to just sitting in a chair all day. I've never seen anyone who can maintain good posture for 8 hours a day. And even if you do, your still weakening your glutes and abs while tightening your hips and calves.
