Diffrient World Chair by Humanscale
Described as a masterpiece of design, the World Chair combines maximum performance and functionality in a design that utilizes one-third the parts and less than half the raw materials of competing high-performance office chairs. The World Chair features an unprecedented combination of performance, sustainability, and simplicity!
The World Chair marks Humanscale’s first all-mesh task chair. The tri-panel backrest hugs the body to provide tailor-made lumbar support, while its mesh seat eliminates contact stress under the thighs. But the 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.
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.
Simplicity: For the User
With only two manual settings, one for seat height and one for seat depth, the World Chair is the ultimate user-friendly sitting experience. All other fittings and adjustments are automatic. Every user is automatically supported at every recline position with the World Chair’s weight-sensitive recline feature. Form-Sensing Mesh Technology provides tailor-made lumbar support without external devices or manual controls. Effortless ergonomic comfort has replaced the knobs, levers, and instructions of the usual office chair.
Simplicity: For the Organization
Many of today’s office chairs come equipped with so many controls and adjustment features they require actual hands-on training. In stark contrast, the World Chair simplicity means users can take full advantage of its ergonomic benefits the moment they sit down, without even thinking about it. With just eight major parts, very little can go wrong with the World Chair over time, which is why it comes equipped with an industry-best 15-year 24/7 warranty. So instead of managing chair training and ongoing maintenance and repairs for employees, organization can focus on managing their business.
Simplicity: For the Environment
Simple is better for the environment too. Minimal-part designs require far less raw material and fewer manufacturing processes and that means less extraction, energy waste, shipping and disposal associated with a product’s life cycle. Weighing just 25 pounds, the environmental impact of the World Chair is roughly half that of an average task chair. In addition, the World Chair is 97% recyclable.

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.
