Key Features
The Diffrient World Chair by Humanscale was designed by Niels Diffrient, who wanted to create the most minimal, full-function task chair possible. This addition to workspaces is both simple and beautiful, following his philosophy that form should follow function. With only two manual settings that eliminate the need for excess knobs and buttons, the rest of this chair is designed to automatically adjust, supporting each person by using their body weight and the laws of physics. A weight-sensitive recline combined with form-sensing mesh technology provides lumbar support, making this chair simple and comfortable to use. The mesh construction continues to the edge of the seat – removing pressure from behind the knees, making it easy to sit for longer without adding stress to the lower body. Made from less parts than a traditional task chair and weighing in at only 30 lbs, this design uses fewer raw materials and manufacturing processes – making it a lightweight and environmentally-friendly choice.
Since its inception in 1983, Humanscale has been a pioneer in pushing design forward in the areas of ergonomics and energy efficiency. Superior performance, effortless operation and excellent quality set their modern office chairs and products apart from the rest, allowing the modern work environment to be more comfortable and less complicated so the individual can focus on the task at hand.
