Diffrient Occasional

designed by Niels Diffrient

Diffrient Occasional is a stackable multipurpose chair that is suitable for a variety of office and group settings. A strong, linear backrest made with proprietary non-stretch mesh creates a three-dimensional form — fitting the user like a perfectly tailored shirt.


About Diffrient Occasional

Diffrient Occasional responds to the sitter and adapts to the contours of the body. Featuring expertly welded joints that create a continuous frame, Occasional is suitable for any office or home environment. It can be configured to match our Diffrient Smart, Diffrient World or Liberty task chairs for a consistent and restrained look.


Ergonomic Comfort

Using the laws of physics as opposed to a manual adjustment, our patented Form-Sensing Mesh Technology provides automatic lumbar support for every user.

Engineered for Longevity

The chair’s high-quality materials and sturdy frame are built to last. Capable of stacking up to five chairs high, Occasional's urethane arms are designed to resist damage — even when moved and stacked.

Customizable Options

Available in a variety of patterns and finishes, you can design Occasional to suit your aesthetic needs. Its restrained and elegant style will blend into any environment.

Design Story

“I keep thinking, 'how much simpler can this be?' and come up with the end result.”

Niels Diffrient, Designer 

Drawing inspiration from the three-dimensional approach tailors take when creating men’s suits, Niels Diffrient wanted to build a minimal mesh chair with a back that automatically fits the user. Every detail on Diffrient Occasional was carefully considered throughout its creation, from its stackable functionality to expertly welded joints that appear clean and smooth to the eye. The result is a simple but beautiful design that raises the standard for multipurpose seating.

Environmental Story

Diffrient Occasional is made predominantly from lightweight, 100% recycled aluminum. For Occasional’s plated-finish option, we use Chrome 3 instead of the hazardous Chrome 6. Humanscale textiles are also developed to be functional without the use of harmful PFC (perfluorinated chemical) coatings typically used for stain resistance.

Finish Options

Monofilament Stripe

Made specifically for our tri-panel, mesh-backed chairs, Monofilament Stripe has an elastic composition that achieves strength through its distinctive weave structure to provide unmatched support. Its classic stripe pattern is available in various striking colors.
