Mechanism-Free Recline Action.


The Diffrient World task chair features an innovative, mechanism-free recline action that utilises the laws of physics to provide personalised support for each individual user. By harnessing the user’s body weight, this groundbreaking technology offers automatic and balanced support throughout the entire range of motion, ensuring maximum comfort and support.

Personalised Back Support.


Diffrient World boasts a backrest that is designed with patented Form Sensing Mesh Technology, which leverages the laws of physics to eliminate the need for a separate lumbar support. This innovative technology ensures that the chair’s backrest conforms perfectly to the sitter’s entire back, providing a custom fit and eliminating the need for manual adjustments. By eliminating pressure points, this feature offers maximum comfort and support to the user.

Comfort-Optimised Design.


The Diffrient World task chair features a lightweight design that replaces the standard cushion seat with a non-stretch, low-abrasion mesh for maximum comfort.

This innovative design solves the enduring problem of hard edges and contact stress, providing a comfortable sitting experience for extended periods of time.
