A unique colorful office chair designed by Neils Diffrient. The Humanscale Diffrient World chair is Humanscale's first entry into the 'all-mesh' task seating category. Renowned designer Niels Diffrient wanted to create the most minimal, full-function task chair ever made. Created with the Humanscale, tried and tested, innovative tri-panel mesh backrest that provides custom back and lumbar support, it is like all of Humanscale’s products, simple, beautiful, and functional. The Humanscale Diffrient World chair design, like other Humanscale seating products, eliminates the need for traditional mechanisms, instead using the laws of physics, and the sitter’s body weight to create the perfect recline functionality. Available in an all-mesh seat version or a version that has a more conventional foam seat pan with a textile overlay. 
  • Pivoting backrest adapts automatically as you recline for optimum lumbar support
  • User maintains near-constant eye level during recline
  • Self-adjusting mechanism free recline

Back Mesh Patterns & Colors (For seat textiles please click on the green 'Fabric Selector' button above)

Catena features a pure, clean weave—free of any additional patterns or motifs—in colors inspired by the rich hues of spices,  which allow the chair to seamlessly integrate into its setting. It’s simple aesthetic makes it a classic design choice for modern and contemporary environments.


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.

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.

 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.

 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.

 82% Polyester, 18% Nylon 


  • Invisible Recline Mechanism: The Humanscale Diffrient World chair uses the laws of physics and harnesses the user’s body weight to automatically provide the right amount of recline for every individual, every time. Its groundbreaking mechanism-free recline action leverages two parts of the chair’s frame to provide automatic, balanced support throughout the full range of motion for maximum support.
  • Responsive Backrest: Diffrient developed the chair’s back using the laws of physics, which eliminates the requirement for a separate lumbar support, which tends to create a pressure point and requires manual adjustment. With patented Form Sensing Mesh Technology, the backrest perfectly conforms to the sitter’s entire back as if custom made for them.
  • Sitting on Air: A truly light-weight chair, the Humanscale Diffrient World chair replaces the standard cushion seat with a low-abrasion, non-stretch mesh. To maximize comfort, Diffrient eliminated the front edge of the chair, solving a perennial problem of hard edges placing pressure on the knees and contact stress behind the thighs, allowing long-term comfort and total supports for every sitter.worldonedims.png
