Humanscale is taking the best features of the classic, renowned World Chair, and simplifying to bring the cost-effective new World One Chair. Featuring the same tri-panel mesh back and weight sensitive recline designed by Niels Diffrient, these defining elements have been updated to bring the technology into a more accessible price point - all while using fewer parts. A high-value task chair with minimal parts, the World One was designed with longevity in mind - guaranteeing it will look as good in ten years as it does today. Get ready to enjoy the most minimal, fully-functional task chair Humanscale has ever made.

Like all Humanscale chairs, the sophisticated design eliminates the need for traditional mechanisms by utilizing the laws of physics, and the sitter's body weight to give the perfect recline.

The Humanscale World One features armrests that attach to the back of the chair in order to easily move with the user, providing an ideal resting spot at any angle.
