The Designer

One of the century’s pre-eminent designers, Niels Diffrient has endeavoured throughout his career to emphasise the “human factors” of industrial design, using ingenuity and intuition to provide consumer products that meet their needs.

His emphasis on meeting human needs was codified in the three volume Humanscale, an influential sourcebook for designers that examined the movements and dimensions of the human body. 

His quest to create workplace environments fitted to the needs of their users; continues unabated with “Liberty,” a task chair that conforms to its user’s shape without an array of knobs and levers. 

Movement is essential for a healthy back. People are spending more time sitting than ever before. Not surprisingly, this increase in sitting has been accompanied by a proportional increase in back problems. Our bodies were designed to move. In fact, movement, more than anything else, provides nourishment for the spine, keeps the joints lubricated and flexible, improves circulation and therefore keeps us comfortable. 

Conversely, when we don’t move, the elasticity of our spine and joints is reduced and our muscles become fatigued. The key to healthy and comfortable sitting is being able to move without restrictions. 

Press Highlights:

“The granddaddy of the ergonomic revolution, Diffrient, 78, has spent his career emphasizing the ‘the human factor’ when designing an object. The first volume of his breakthrough book, Humanscale, was published in 1974, altering the way in which industrial designers approached projects, urging them to consider usability as much as they were considering aesthetics. Diffrient’s Freedom chair, first presented in 1999, became a quick hit among purveyors of design and aching-back office workers alike—eight years later, it’s still considered to be on the forefront of comfort and style.” – The Tastemakers, 2007 

“The world’s simplest and smartest office chair. Almost magically, Freedom adjusts itself to the greatest range of human performance without knobs, locks or levers.” — AXIS (Japan), Nov-Dec 1999

“The jurors were awed by the mechanics, wowed by the comfort and overcome with excitement about the possibility of changing the contract-seating market forever.” — I.D. Magazine, Design Review 2000

“[The] combination of ergonomics and aesthetics … marks the true genius of the Freedom chair. The ergonomic properties and comfort levels are second to none.” — Mix Interiors (UK), February 2000

“The [Freedom] chair adapts naturally to the geometry of the human body. The [mechanism] operates dynamically and stops automatically in the correct position.” — DOMUS (Italy), March 2000

“Diffrient’s chair [will] save a great many people from a great deal of unnecessary, life-degrading pain. Design has no higher aim. Plus, let’s be honest: The Freedom chair looks amazingly cool!” — Wired, July 2000

“The [Freedom] chair is sensational.” — Fortune Small Business, June 2001 “Five stars! Worth every cent, the Freedom task chair removes at least the physical discomfort of your workday.” — Business 2.0, June 26, 2001

“For the last few years, the gold standard in office seating has been set by … the Freedom chair by Humanscale.” — New York Times, October 3, 2002

“Elegantly and effortlessly, the Freedom chair is changing the way people sit and the way people think about furniture.” — Buildings, December 2002 FREEDOM PRESS HIGHLIGHTS 8

“This ergonomic office chair feels so good, the two of you will want to get a room.” — Popular Mechanics, January 2003

“Chairs reflect the character of their designer. Niels Diffrient is clever, pragmatic, honest, personal and generous. I sit on his Freedom Chair every day and it makes me optimistic about the value of design.” — Rob Forbes, Founder of Design Within Reach, 2003

“The most impressive characteristic of Diffrient’s chair is how intuitive it is. At last, this is a chair that offers some support for all those who never adjust the multitudinous knobs on their office seating, and wouldn’t know what to adjust them to if they did.” — Blueprint, April 1, 2003

“You can’t get more comfortable in a vertical position.” — Andrew Tilin, “Our picks for … office chairs,”, September 2007

“You’ll marvel at the simple sophistication...” — Andrew Tilin, “Our picks for … office chairs,”, September 2007

“So it’s not exactly cheap—but when you spend the majority of your life in a desk chair, it’s probably worth the splurge. The uber-ergonomic Humanscale Freedom uses a counter-balance mechanism to provide the exact amount of support your body requires, has a specially contoured back design, and works without a half-dozen pumps and controls, so that sitting easy can be just that.” — Abby Seiff,

“We really had a hard time deciding between Humanscale and Herman Miller, two companies that seem to compete like Coke and Pepsi. In the end … we went with the Humanscale [Freedom chair] and its supportive headrest as the best option.” — John M. Guilfoil,

“Straighten up and sit right,” Boston Globe, February 8, 2009 “Damn you Humanscale! Damn you for making such a ridiculously comfortable chair.” — Yoni Freedhoff, M.D.,
