The World Chair marks Humanscale's first foray into all-mesh task seating. Like its mesh-backed forerunner, Liberty, the World chair's tri-panel backrest hugs the body to provide tailor-made lumbar support, while its mesh seat eliminates contact stress under the thighs. But the World’s major innovation is its mechanism-free recline action, which leverages two parts of the chair’s frame and the laws of physics to provide automatic, balanced support throughout the full range of recline. No chair is more intuitive, creating the ultimate user-friendly sitting experience.
The first office chair that adjusts without a lever! Intuitive motion follows your body movements to automatically find the ideal angles to optimally support your body.

  • "Virtual Mechanism"; two part frame uses body weight to adjust chair angles
  • Frameless front seat edge eliminates contact stress behind the knees
  • One year warranty on motor and electrical parts
  • Form-sensing mesh creates body-contouring, adjusting lumbar support
