    The Design Story

    Using his insight of how tailors take a three dimensional approach when designing men’s suits, Niels Diffrient created a minimal mesh task chair with a back that will automatically conform to the user. Working together with textile designer Elizabeth Whelan, they came up a flexible but strong non-stretch mesh, so the backrest takes on the shape of the sitter. The end result is the Diffrient World chair, a task chair that is simple but beautiful, and supports the user instantly.

    "If every chair was made the way the World Chair was, we would cut in half all the material used for task chairs."

    Niels Diffrient, Designer

    Dash Mesh

    Dash is one of the newest meshes available in the Humanscale line. It is characterized by its strength and durability.

    Catena Mesh

    Catena offers a unique pattern in a variety of modern colors.

    Pinstripe Mesh

    Pinstripe offers a simple stripe pattern in a variety of enlivening colors.

    Fourtis - Grade 1

    Inspired by the Latin word fortis, meaning strong, this fabric is the ultimate ratio of durability and flexibility thanks to a unique weave of two-blended colors, and offering a four-way stretch.

    Corde 4 - Grade 1

    Constructed from cotton, Corde 4 includes a four-way stretch and a small, modular weave. The result is a dimensionally ribbed surface on the face of the fabric that remains soft to the touch.

    Lotus - Grade 1

    This four-way stretch textile is water repellant and easy to clean, making it an ideal textile for healthcare and hospitality environments. Its polyurethane finish with nylon backing boasts a soft texture while offering exceptional durability. It exceeds all standards for contract upholstery and healthcare tests.

    Sensuede - Grade 3

    Sensuede was developed to be the best and most luxurious engineered suede available. The faux suede's soft touch comes from the use of breathable and wrinkle resistant recycled microfibers that are finer than a human hair but are extra-strong, resulting in a very resilient fabric. This material also was selected because of its environmentally sensitive content and manufacturing process.

      Best chair I've ever experienced.

      Posted by BC on Feb 24th 2016

      This the best chair that I've ever had the chance to use. Sadly, it's just a loaner chair, but it really is amazing. I wish I had one for both my office and home use.

      The only buttons on it are below the seat so that you can choose to raise it or lower it. Only noticeable when you look for them.
      The seat feels as if you are sitting in a cloud, or possible air, while also giving plenty of support.
      It fits my smaller frame. I am light and most chairs are harsh on both size and also harshness of support. This fits perfectly.
      The automatic recline adjusts to any level that I decide when I sit back. It doesn't just fall backwards like someone previously suggested.

      It's too expensive for me to buy one for my home.

      18 months of using this chair

      Posted by Jack Burns on May 29th 2015

      I began experiencing back pain shortly after starting to use this chair, I thought there is no way it's the chair, I took extreme measures to find out every other possible source of my pain, I thought it was tendonitis, my mattress, any other possible thing after all this is the "BEST" chair since sliced bread, well came to find out after months and month that is in fact the chair, it offers no upper back support the self recline just goes to full recline it's got no resistance to give support, forcing the user to lean forward when using a PC, lead to serve back pain to the point of nerve damage

      Very comfortable

      Posted by Ed on Jan 11th 2015

      I'm very pleased with this chair; it's quite attractive and equally comfortable for both the seat and back. All details appear to be well designed, and it arrived within days in the color/configuration as ordered. Only time will tell, but I believe it will hold up well under daily use.

      A bit expensive, but a fine chair nonetheless.
