This is Humanscale's first venture 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 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 – offering the ultimate user-friendly sitting experience.
