Frequently referred to as the granddaddy of ergonomic design, Niels Diffrient channels his knowledge of engineering, architecture and the human form to create his highly functional, aesthetically timeless task chairs. His Diffrient World Chair (2008), with its simplicity and intuitive design, epitomizes his approach to task seating. Made from just eight major parts and weighing under 25 pounds, the World Chair is designed to automatically conform to your shape – allowing you to spend more time thinking about work and less time thinking about your chair. Its weight-sensitive recline operates without a mechanism, relying instead on the laws of physics and interaction of the frame’s components. The form-sensing mesh on the seat and back conform to the user’s body, offering instant support without the need for manual adjustments. Like all Diffrient designs, environmental impact is a consideration, which is why this chair is 95% recyclable. Made in U.S.A.
