Humanscale® Diffrient World® Chair
Designed and engineered for ergonomic back support and comfort without thought or effort on your part, the Diffrient World chair by Humanscale uses a body-hugging tri-panel mesh backrest and the laws of physics in place of complicated manual controls to achieve intuitive, self-adjusting lumbar support and a user-friendly sitting experience.
Despite its slim and stylish profile, the World chair can hold users up to 300 lbs., as well as accommodate a wide range of body types.
The chair is available as an armless model, or with fixed or adjustable armrests. Choose from many colors, fabrics and two frame options. An optional upholstered seat cushion is also available.
Features
Form-Sensing Mesh technology
Tri-panel, non-stretch mesh construction creates body-fitting contours and self-adjusting lumbar support for a customized fit.
Weight-Sensitive Recline
By using the sitter's body weight and the laws of physics, the World chair's mech-free recline action automatically adjusts to the needs of each user with appropriate levels of resistance without locks, dials or manual controls.
5-star aluminum base
Adjustable Armrests (Optional)
The adjustable armrests move with the sitter for continuous ergonomic support during recline.
Manufacturer's Warranty
The Diffrient World chair comes with a 15-year manufacturer's warranty.
Environmental Benefits
Made from just 80 parts overall — less than one-third the parts of traditional task chairs. As a result, two to three World chairs have the same overall environmental impact as a single traditional task chair. 95% of its components can be recycled.

Humanscale History

Humanscale stands for: 1) Superior performance 2) Effortless operation 3) Excellent quality The company requires that their products solve a problem, are comfortable and less complicated, so people can focus on their task at hand.
Humanscale achieves superior performance by designing furniture in accordance with how people actually work — how they sit, type and move at their desks. Since people don’t think about their posture or the physical relationship of their body to objects while they work, Humanscale products do it for them. Their products react to peoples’ movements and adjust to their bodies, instead of the other way around for unsurpassed comfort. Although familiar in appearance, Humanscale products function differently, intuitively, with no learning curve and they are designed for rigorous use and maximum durability. Most are guaranteed for life.
Humanscale’s development of high-performance ergonomic office tools began in 1983. Beginning with its first product — an anti-glare filter that improved the visibility of monochrome monitors in the early 1980s — the company has methodically designed some of the most innovative products in the industry. In the 1990s with the introduction of high-performance articulating keyboard systems, Humanscale made a very significant contribution to the ergonomic industry. In 1999, Humanscale took the contract furniture industry by storm with the introduction of the Freedom chair, designed by ergonomics pioneer Niels Diffrient. The revolutionary seating solution broke new ground by combining unprecedented functionality with minimal manual controls, utilizing dynamic mechanisms that respond to the requirements of each individual user automatically. In 2009, Humanscale sold its millionth Freedom chair.
