Designed with the same innovative tri-panel mesh backrest and weight-sensitive reclined as its predecessor, the World One chair is a cost-effective solution that delivers unmatched ergonomic support and the ultimate user-friendly sitting experience. Renowned designer Niels Diffrient wanted to create the most minimal, full-function task chair ever made. Created with the Humanscale, tried and tested, innovative tri-panel mesh backrest that provides custom back and lumbar support, it is like all of Humanscale’s products, simple, beautiful, and functional. The Humanscale Diffrient World chair design, like other Humanscale seating products, eliminates the need for traditional mechanisms, instead using the laws of physics, and the sitter’s body weight to create the perfect recline functionality. The World One comes in just one model and one color to keep it simple and affordable. Please watch the video to truly appreciate the Humanscale design.
