Diffrient World Task Chair

Designed by Niels Diffrient
Made by Humanscale


Diffrient World is Humanscale's first foray into all-mesh task seating. Designer Niels Diffrient wanted to create the most minimal, full-function task chair ever made. With an innovative tri-panel mesh backrest that provides custom back and lumbar support and a lightweight design, Diffrient World is, like all of Humanscale’s products, simple, beautiful and functional. The design eliminates the need for traditional mechanisms, instead using the laws of physics and the sitter’s body weight to offer perfect recline for each individual sitter. Diffrient World offers the ultimate user-friendly sitting experience.

Niels Diffrient designed Diffrient World to offer ease of use and effortless functionality. With weight-sensitive recline that adjusts automatically and armrests that are attached to the back of the chair so they move with the user for ergonomic comfort, Diffrient World provides custom comfort for every sitter. A high quality, affordable task chair with minimal parts, Diffrient World was built with longevity in mind and will look as good in ten years as it does today.
