A smarter way to sit

Quick ship chairs ship in about 10 business days. For custom configurations not available on this page check out the Smart Custom Order page.

Humanscale has once again partnered with the legendary designer and engineer Niels Diffrient to create the all new Diffrient Smart chair. Featuring Humanscale’s patented weight-sensitive, mechanism-free recline, Smart automatically adjusts to the body weight of each sitter to provide perfect recline support.

Available with 4D armrests, the Smart chair works with each user to create a comfortable seating option with minimal manual adjustments.

  • Rated for users from 100lbs to 300lbs
  • 15 year, 24/7 warranty
  • Only 2 manual settings, all other fitting and adjustments are automatic
  • About half the environmental impact of other office chairs
  • 97% recyclable
  • Cal 133-approved
  • May contribute to numerous LEED credits
  • Shipping dimensions: 40" x 28" x 28" 25lbs

The upholstery and mesh options listed in the dropdown menu are currently approved for use with the Smart chair. Please check back periodically as we will update the available options as they are approved by Humanscale.

For a complete list of Humanscale upholstery and mesh options, please visit our Humanscale upholstery page.

1. Self-Adjusting Recline

  • Using the laws of physics, the mechanism-free design automatically provides customized support and resistance based on each user
  • Intelligent counter-balance recline mechanism automatically provides the right amount of support through the full range of recline motion, regardless of user size and weight
  • During recline, the angle between torso and legs opens up for better body function

2. Pivoting Backrest

  • Extra motion of the backrest during recline automatically adjusts to the changing needs of the spine.
  • Provides additional lumbar support as needed

3. Form-sensing Mesh Technology

  • Tri-panel, non-stretch mesh construction creates body-fitting contours and self-adjusting lumbar support for a customized fit
  • Low-abrasion mesh protects clothing.

4. Contoured Seat Cushion

  • Carefully sculpted to match body contours
  • Increased contact area reduces pressure points
  • Modular for easy replacement

6. Body Fit
