Humanscale Diffrient World Chair

The Humanscale Diffrient World Chair is a mesh task seat from designer Niels Diffrient; created with a desire to be the most minimal, full-function task chair ever made.

It has an innovative tri-panel mesh backrest that provides custom back and lumbar support and a lightweight design. Diffrient World is, like all of Humanscale’s products, simple, beautiful and functional. The design eliminates the need for traditional mechanisms; instead using the laws of physics and the sitter’s body weight to offer perfect recline for each individual sitter. Diffrient World offers the ultimate user-friendly sitting experience.

Niels Diffrient designed Diffrient World to offer ease of use and effortless functionality. With weight-sensitive recline that adjusts automatically and armrests that are attached to the back of the chair so they move with the user for ergonomic comfort; Diffrient World provides custom comfort for every sitter. Diffrient World is built with longevity in mind, and accordingly offers high quality and value with minimal parts.

The chair eliminates the requirement for a separate lumbar support, which tends to require manual adjustment. With patented Form Sensing Mesh Technology, the backrest as a result perfectly conforms to the sitter’s entire back. Please refer to product images for the mesh colours available

A truly lightweight chair, Diffrient World replaces the standard cushion seat with a low-abrasion, non-stretch mesh. To maximize comfort, Diffrient eliminates the front edge of the chair; as a result solving a perennial problem of hard edges. This in particular avoids placing pressure on the knees and contact stress behind the thighs.
