Humanscale has always stood out for sleek, simple, and high-performance products, and Diffrient World is no exception. This all-mesh office chair by designer Niels Diffrient was created to provide optimal support. Diffrient World has a tri-panel mesh backrest for custom back and lumbar support. This design does not use traditional mechanisms but the laws of physics and the user’s body weight to suit their optimal recline. Diffrient World keeps the user’s comfort and well-being in mind; it might as well be the most comfortable and modern office chair you’ve ever used! We can help you revolutionize your office design NYC with all-new furniture. We’re just one click away from you. Type in “office furniture near me” and find us.

Innovative, Ergonomic Mechanisms

Diffrient World has a modern way of doing things. It features the Invisible Recline and Responsive Mechanisms. The former harnesses the sitter’s body weight to adjust recline. The free-recline action doesn’t use a mechanism but leverages two pieces of the chair’s frame to adjust tailored balanced support. The latter has a patented Form Sensing Mesh Technology, an advanced system that replaces the need for separate lumbar support.

Forget About Levers and Controls

There are no manual adjustment mechanisms on Diffrient World except for seat height and seat depth. The backrest conforms ergonomically to each individual user’s body. On the Diffrient World chair, armrests are attached to the back, which allows them to move with the user. This means custom mobility at all times.

Super Lightweight and Supple

Diffrient World weighs only 30 pounds. The ensemble of materials it uses provides lightweight but durable performance. The seat is made of low-abrasion, non-stretch mesh with no front edge, to relieve the pressure on the back of the upper thigh or the knees, thus generating longer-lasting comfort and allowing blood circulation to flow.
