Diffrient World delivers all-mesh elegance, merging premium lumbar care with adaptability. Niels Diffrient’s full-function ergonomic task chair looks at home in any modern office and offers customized back support through a physics-powered design and tri-panel mesh. Features With just eight major parts, Diffrient World is built to last. Requiring minimal maintenance, World comes with a 15-year, 24/7 warranty. In other words, the chair’s simplicity reduces the need for ongoing maintenance and repairs, making it even easier to own. Diffrient developed the chair’s back using the laws of physics, which eliminates the requirement for 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. The world's 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 comfort. All-mesh design fits handsomely into any office – no matter where you work. Tri-panel mesh back offers intelligent support for your unique pressure points. The lightweight design makes it exceptionally easy both to assemble and relocate. About the design: Niels Diffrient designed Diffrient World to offer ease of use and effortless functionality. With a 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. A high-quality, affordable task chair with minimal parts, Diffrient World was built with longevity in mind and will look as good in ten years as it does today. What is a net positive product?

Invisible recline mechanism: Diffrient World 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 bracket: Diffrient developed the chair’s back using the laws of physics, which eliminates the requirement for 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 lightweight chair, Diffrient World 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 support for every sitter. Design story: "I’ve always insisted that the back adjusts to the person and we have this unique Form Sensing Mesh that will accommodate any body shape and give you appropriate back support. Whether you’re short, tall, wide, or narrow, the back will accommodate you." Niels Diffrient, designer. Inspired to create a minimal but functional mesh task chair with curved lines and a contemporary aesthetic, Niels Diffrient designed Liberty. As with the Diffrient World chair, Liberty features an innovative tri-panel non-stretch mesh backrest, which Diffrient said was based on the concept of a tailored men’s shirt. He worked closely with textile designer Elizabeth Whelan to create a mesh that was strong and supportive but still flexible.
