The Diffrient World chair is Humanscale’s first foray into all-mesh task seating. Designer Niels Diffrient wanted to design the most minimal, full-function task chair ever created. 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 and stunningly functional. This design eliminates the need for hard to adjust mechanisms as it is self-adjusting. Diffrient World offers the ultimate user-friendly work chair experience. Warrantied for 15 years by Humanscale and certified for 24/7 multi-shift usage for sitters up to 300 pounds.
