Humanscale Sets New Bar with Ultra Simple Task Chair

Diffrient World Chair Combines Exceptional Design, Comfort and Sustainability

NEW YORK, April 1, 2009 ­— Humanscale’s Diffrient World chair by legendary designer Niels Diffrient will debut at NeoCon 2009, June 15 – 17. Utilizing the laws of physics instead of complex mechanisms and controls, the Diffrient World chair represents ultimate simplicity in a high-performance task chair.
Made from just eight major parts and weighing less than 25 pounds, the new chair incorporates Humanscale’s signature weight-sensitive recline to offer recline resistance that is automatically customized for every user. Like its older sibling, the award-winning Liberty chair, the Diffrient World chair features Form-Sensing Mesh Technology that ensures perfect lumbar support for every user without the external, manually adjusted lumbar devices found on all other mesh chairs. Additionally, a mesh seat pan with a frameless front edge provides all-day comfort with soft support under the thighs.
By achieving high levels of performance and functionality with just 80 parts overall—less than one-third the parts of traditional task chairs—the Diffrient World chair is assured of long-term durability that far exceeds that of traditional chairs. Quite simply, fewer parts, controls and mechanisms translate into fewer things that can go wrong over time. As such, the Diffrient World chair is backed by a 15-year warranty, including two- and three-shift usage, which makes it the best warranty in the industry. The Diffrient World chair is also unmatched in sustainability. Its light weight and minimal-part design significantly reduce its environmental impact by requiring less raw material and fewer manufacturing processes for its creation.

As a result, two to three Diffrient World chairs have the same overall environmental impact as a single traditional task chair. Its durability as well as modularity for easy in-field upgrades further minimize its carbon footprint by ensuring a long life of service. And when the chair does finally need to be replaced, its simple design with so few parts makes disassembly a snap so that 95% of its components can easily be recycled.

Options on the Diffrient World chair include fixed or adjustable armrests that move with the sitter to offer continuous ergonomic support during recline. Also available is an upholstered seat cushion that floats on a mesh support structure for exceptional sitting comfort.

Full production of the Diffrient World chair will begin in June. List pricing starts at $740 and the chair will debut with two mesh styles, a variety of mesh colors and several frame color options, including Humanscale’s new architectural white.
