Diffrient Smart Drafting Chair
Compliments any Environment.
Humanscale Diffrient Smart drafting chair is an intelligent mesh task chair with a striking linear aesthetic that complements any environment. Engineered to provide automatic lumbar support for every user, as well as simplicity and ease of use, Diffrient Smart offers comfort, style and flexibility, and uses Humanscale’s revolutionary Form-Sensing Mesh Technology and mechanism-free recline for perfect support for every user.
Ease Of Use.
Featuring Humanscale’s weight-sensitive, mechanism-free recline, Smart automatically adjusts to the body weight of each sitter to provide perfect recline support. Using the laws of physics, all the user has to do is sit and the chair will provide the correct amount of tension for their shape.
Linear Visual Design.
Free of manual controls, Diffrient Smart has a striking, sleek aesthetic, and its U-shaped back makes it the perfect fit for any high-design environment. With linear lines in the backrest and strong mesh for maximum support, it’s the ideal task chair for the modern, active workspace.
Tailored Backrest.
To ensure every person who sits in Diffrient Smart would have perfect lumbar support, Diffrient created a tri-panel mesh backrest to automatically adapt to the user’s needs. Eliminating the need for complicated adjustments and external lumbar devices, Diffrient Smart uses Form-Sensing Mesh technology for easy, ongoing comfort.
