Reinventing the chair.... Again!

Special order World Chairs require a 4 week lead time.

Humanscale has once again partnered with the great chair designer and engineer Niels Diffrient to create the all new Diffrient World chair. The patent-pending form-sensing mesh technology coupled with a light frame and unmatched ergonomic design already have the Diffrient World being called "the ultimate chair".

Humanscale has always focused on creating products with unmatched functionality and performance and at the same time keeping physical usage simple and practical. The Diffrient World chair features the perfect combination of cutting-edge design, simplicity of use, and component sustainability.

Designing a chair that meets the highest Humanscale quality standards and matches the ergonomics and comfort of both the Liberty and Freedom chairs is no easy task. Now, imagine designing that same chair with as few parts as possible and while keeping the environmental in mind. It took one of the world's greatest designers over 10 years to develop such a chair. At only 25 pounds, with only 8 major components, and using nearly 100% recycled materials, Humanscale introduces the simplest, smartest and most sustainable task chair on the planet.


  • Designed to fit over 95% of the office population, from the 5' woman to the 6'4" man
  • Rated for users from 100lbs to 300lbs
  • 15 year, 24/7 warranty
  • Only 2 manual settings, all other fitting and adjustments are automatic

  • 97% recyclable
  • Cal 133-approved
  • May contribute to numerous LEED credits
  • Shipping dimensions: 40" x 28" x 28" 25lbs
