Humanscale Diffrient Smart

Designer: Niels Diffrient

A smart chair adapts to your weight and shape automatically, as if the chair were made for you personally.

Featuring a unique linear design, the Diffrient Smart chair is ideal for any high-design environment. Created with Humanscale’s revolutionary Form-Sensing Mesh Technology, Diffrient Smart’s tri-panel backrest fits like a perfectly tailored shirt to provide exceptional lumbar support. Using Humanscale’s weight-sensitive, self-locking recline mechanism, Diffrient Smart automatically adjusts to each sitter and provides perfect support to any posture. Diffrient Smart is also available in Diffrient Smart Plus with a wider seat and additional support.

The Diffrient Smart chair is ideal for Workstations, Conference Rooms, Reception Areas, and Home Offices.

Environmental Story

The Diffrient Smart chair was designed with a constant and genuine focus on its environmental impact at every stage of its development. The best designs in the world achieve more with less, and sustainability is the natural result of this focus.
The Diffrient Smart chair’s lightweight design minimizes the environmental impact of its shipping. Its use of highly recyclable aluminium and its simple, modular design makes it easy to disassemble and maintain rather than replace the chair completely. The Diffrient Smart chair is GREENGUARD Indoor Air Quality, GREENGUARD Gold and level® 3 certified.
