Humanscale’s World One Task Chair, designed by Niels Diffrient and retooled for professional home and small office use.

No chair is more intuitive, creating the ultimate user-friendly sitting experience.

  • Designed to offer ease of use and effortless functionality, providing custom ergonomic comfort for every sitter
  • The most minimal, full-function task chair ever made – just 2 manual settings – 1 each for seat height and seat depth
  • Innovative tri-panel Black mesh backrest conforms to your entire back providing custom back and lumbar support
  • Weight-sensitive recline action provides automatic, balanced support at all points throughout recline
  • Height adjustable Duron Arms – durable polyurethane arm with a Technogel core for added comfort
  • Armrests are attached to the back of the chair so they move with the user for ergonomic comfort
  • Frameless front edge of seat eliminates contact stress behind the knee
  • Dual-wheel office casters for greater mobility
  • Quick assembly


Chair is slightly different from the standard World Chair model. Mesh is a little less smooth, Casters are standard office casters rather than Humanscale’s more designed style and there are no finish options.


SmoothRoll Office Chair Wheels Set of 5Add SmoothRoll Casters – Protects flooring and provides smooth ride



 A high quality task chair with minimal parts, Humanscale’s World One Task Chair provides custom comfort for every sitter. Built with longevity in mind, the World Chair will look as good in ten years as it does today.
