Diffrient World Chair by Humanscale
designed by Niels Diffrient
The world of furniture designers always faces a trade-off between simplicity and versatility when creating a new product. An ergonomic chair that is simple and intuitive usually sacrifices versatility and adjustability, while a highly versatile chair is rarely simple to use. In the Diffrient World Chair, ergonomics pioneer and renowned industrial designer Niels Diffrient has achieved an unprecedented combination of simplicity and versatility.
The World Chair has two manual adjustments- one for seat depth and one for seat height, but these aren't the only elements of the chair that adjust. All the other adjustments react automatically to your movements. Its patented form-sensing 3-panel mesh back conforms to your back, eliminating the need for the often intrusive external lumbar support. It also features a weight-sensitive recline mechanism that delivers support at every point of recline.
1. Self-Adjusting Recline
- Eliminates the need for recline locks and resistance knobs, creating a clean aesthetic
- Regardless of the user's weight, the World Chair's recline mechanism delivers an appropriate amount of support and resistance during recline

2. Pivoting Backrest
- Extra backrest motion automatically adjusts to the movements of the spine
- Adapts automatically to provide additional lumbar support as needed
3. Form-Sensing Mesh Technology
- No external lumbar devices to adjust depending on your sitting position
- Trip-panel, non-stretch mesh construction creates body fitting contours and self-adjusting lumbar support for automatic, customized fit
- Low-abrasion mesh protects clothing
- Can be replaced as needed if another user should the World Chair changes users
4. Form-Fitting Seat
- Frameless front edge eliminates contact stress behind the knees
- Adjustable seat depth in the World Chair accommodates a wide range of users
- Low-abrasion mesh protects clothing
- Adjustable or fixed armrests connect to the backrest instead of the seat to stay with the body during recline

With a resume that includes collaboration with icons Eero Saarinen and Marco Zanuso, a background in aeronautical engineering, and numerous design awards, Niels Diffrient is undoubtedly one of the most influential designers of the past 50 years.
Born in 1928 in Star, Mississippi, Diffrient attended Wayne State University and eventually enrolled in the Cranbrook Academy of Art, where he won the First Medal of Design three times during his tenure there. After traveling and working in Europe thanks to a Fulbright Scholarship, Diffrient began work at the design firm Henry Dreyfuss Associates, where he would stay for 25 years. While there, he co-authored the three-volume publication Humanscale. This work summarized his design principles which were rooted in the belief that the human body should drive design for products that humans will interact with. In his own words: "A design should look good and be appealing, but without compromising human factors. Aesthetics should enhance the technical side, not deter from it."
