Humanscale Diffrient World Chair2

Return to HumanScale

Humanscale's Diffrient World features all-mesh task seating designed by Niels Diffrient, who 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. Available in multiple frame colors and mesh and fabric combinations. Free shipping to the continetal US.

The Diffrient World chair has just two manual settings—one each for seat height and seat depth.

All other ttings and adjustments are automatic.

With its weight-sensitive recline, the Diffrient World chair automatically supports every user at every recline position. And its Form-Sensing Mesh Technology provides tailor-made lumbar support without external devices or manual controls.

That means we’ve replaced knobs, levers and instructions with effortless ergonomic comfort.
