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.

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.

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.

Backrest Mesh:



Silver Check

This brilliant weave of monofilament strands and silver-coated yarns offers resiliency and
durability. The award-winning mesh textile was designed to provide optimal ergonomic
support and comfort by melding strength and flexibility. Like Humanscale's other meshes,
Silver Check has a low abrasion factor and is extremely gentle on clothing.

Content: 74% Polyester, 26% Nylon


Monofilament Stripe

This award-winning mesh textile was designed to provide optimal ergonomic support and comfort by melding strength, flexibility and resiliency. Using only monofilament yarns that are thin and strong, a simple but classic stripe pattern is achieved through weave structure and yarn placement. This pattern has slight elasticity, but terrific memory.

Content: 82% Polyester, 18% Nylon



Dash-one of the latest mesh innovations from Elizabeth Whelan Design-was inspired by the way in which the color appears and then disappears, creating a colored "dash" across the fabric surface. Dash combines a variety of elements to be as strong, lightweight and responsive as possible. With a distinct pattern and small scale, Dash carries color brilliantly and densely for a beautiful result.

Content: 87% Polyester, 11% Nylon, 2% Acrylic



Pinstripe is a lightweight mesh, that still manages to provide the strength and support of a much heavier mesh, by using two different monofilament stretch yarns to provide firmness and excellent recovery of the fabric. Only the pinstripe yarns take the dye, and the monofilament yarns are grey instead of black, giving a more neutral background to the pattern and allowing light to pass through the fabric.
