Humanscale World One

World One is an updated version of Niels Diffrient’s renowned World chair, the most minimal, yet fully functional task chair ever made. Featuring the same innovative tri-panel mesh backrest and weight-sensitive recline as its predecessor, World One is a cost-effective solution that delivers highly engineered ergonomic support and the ultimate user-friendly sitting experience.

Like all Humanscale chairs, World One’s design eliminates the need for traditional mechanisms by using the laws of physics and the sitter’s body weight to offer a perfect recline. World One features armrests that are attached to the back of the chair and move with the user, providing custom comfort throughout the workday. A high-value task chair with minimal parts, World One was built with longevity in mind to look as good in ten years as it does today.

  • Non-stretch, tri-panel mesh construction provides body-fitting contours, and self-adjusting lumbar support for an automatic fit
  • No unnecessary levers, locks, or tension springs
  • Easy size adjustments fit an incredible range of body shapes and sizes
  • Front edge is frameless to eliminate contact stress at the back of the knees
  • Comes with standard hard casters for carpet
