Diffrient World Chair

Diffrient World marks Humanscale's first foray into all-mesh task seating. Like its mesh-backed forerunner, Liberty, the Diffrient World chair's tri-panel backrest hugs the body to provide tailor-made lumbar support, while its mesh seat eliminates contact stress under the thighs. But Diffrient World’s major innovation is its mechanism-free recline action, which leverages two parts of the chair’s frame and the laws of physics to provide automatic, balanced support throughout the full range of recline. No chair is more intuitive, creating the ultimate user-friendly sitting experience.

Simplicity: For the User
The Diffrient World chair has just two manual settings—one each for seat height and seat depth.
All other fittings and adjustments are automatic.
With its weight-sensitive recline, the Diffrient World chair automatically supports every user at every recline position. And its Form-Sensing Mesh Technology provides tailor-made lumbar support without external devices or manual controls.
That means we’ve replaced knobs, levers and instructions with effortless ergonomic comfort.

Simplicity: For the Organization
In stark contrast to other task chairs—with so many controls and adjustments that they require hands-on training—the Diffrient World chair’s simplicity means that users can take full advantage of its ergonomic benefits the moment they sit down, without even thinking about it.
So instead of managing chair training for today’s and tomorrow’s employees, organizations can focus on managing their business.
And with just eight major parts—only 80 overall—very little can go wrong with the Diffrient World chair over time. That’s why it comes with an industry-best 15-year 24/7 warranty. In other words, the chair’s simplicity reduces the need for ongoing maintenance and repairs, making it even easier for an organization to own.

Simplicity: For the Environment
Weighing just 25 pounds and made of one-third the parts of traditional task chairs, the Diffrient World chair requires far less raw material and fewer manufacturing processes—and that means less extraction, energy, waste, shipping and disposal associated with its lifecycle.
In fact, the environmental impact of the Diffrient World chair is roughly half that of an average task chair.
Plus, its modular design further boosts its already-long serviceable life with easy in-field upgrades and part replacements. By the way, it’s 97% recyclable too.

1. Can the Diffrient World chair be ordered with adjustable arms?
Yes, the Diffrient World chair currently comes with fixed arms, adjustable arms, and an armless model.

2. Why is non-stretch mesh preferable to stretchy mesh? Wouldn't stretchy mesh be more comfortable?
A single panel of stretchy mesh pulled tight around a frame cannot be contoured to the shape of the human back, and therefore cannot provide adequate lumbar support. This leads to discomfort over time. Non-stretch mesh displaces instead of stretches, and provides support for users of all sizes.

3. Are the mesh textiles for the Diffrient World chair gentle on clothing?
Each of our mesh textiles was specifically designed to be gentle on your clothes. Unique to our industry, Humanscale performs a reverse Wyzenbeek test on all of our mesh textiles to ensure that they will not damage clothing. We look at how our mesh abrades three different clothing textiles compared to a standard #10 cotton duck as the abradent. These results show that our mesh textiles are far gentler on your clothing than cotton duck.

5. Can a mesh-backed chair provide adequate lumbar support?
Like its mesh-backed predecessor, Liberty, the Diffrient World chair uses Form-Sensing Mesh Technology to provide perfect lumbar support for everyone automatically - without the need for manual adjustments or external lumbar devices. With Diffrient World, three panels of non-stretch mesh are sewn together to create a contoured shape optimized for the human back, creating ultimate body-hugging support.

6. Why are there no levers or controls under the seat of the Diffrient World chair?
The Diffrient World chair is the ultimate user-friendly task chair. It features just two manual controls, for seat height and seat depth. All other controls are intuitive, so there is no need for levers and other controls under the seat.
