Design By Niels Diffrient (1928–2013)

Niels Diffrient was a pioneering industrial designer known for his human-centered approach and belief that design should be intuitive and effortless. Often called “the last of the mid-century modernists,” he focused on simplicity, allowing form to follow function in its purest sense. A Cranbrook Academy graduate alongside Charles and Ray Eames and Eero Saarinen, Diffrient went on to shape some of the most iconic products of the 20th century. His work at Henry Dreyfuss Associates helped define modern industrial design, while his research into human factors redefined how products support the body. His partnership with Humanscale introduced a new standard in seating, creating designs that automatically adapt to the user. Diffrient’s legacy lives on in products that are simple, timeless, and designed to improve the human experience.

    I've been using this all

    I’ve been using this all day for sample prep and it’s sooo comfortable. The seat makes me have great posture, way better than those old lab chairs!

    Feels a lot better

    Casters roll smoothly over tile, and I can move between workstations without strain. My back feels a lot better since switching from my old chair.

    Height adjustment works well

    The height adjustment works well for our variable bench heights. I can sit low or raise it to reach instruments without straining my shoulders.

    Saddle style makes me

    Great product. The saddle style makes me sit upright without thinking about it. I’ve recommended it to colleagues in my department already.
