What ergonomic chair works best for people who move around a lot while sitting?

Active mover ergonomic chair specification at OfficeFurniture2go.com uses dynamic back mechanisms: LiveBack (Herman Miller), FlexBack (Steelcase), or spring-loaded lumbar. These mechanisms track spinal movement rather than resist it — exactly right for users who move constantly. Lighter tilt tension (2–3 on a 1–5 scale) and mesh backs maximize responsiveness.
