Care, Maintenance & Longevity

  • Upholstery

    Care instructions vary depending on the selected upholstery. Vacuum regularly using a soft brush attachment to remove dust and prevent dirt from working into the fibers. For spills, act quickly — blot liquids with an absorbent cloth before they set. Stains should be removed by gently dabbing with a lint-free cloth or sponge dampened with clean, warm water. If necessary, add a small amount of mild dish soap, then finish by dabbing with clean water. Avoid rubbing, as this may damage the textile surface. For wool textiles, professional dry cleaning is recommended for anything beyond surface stains. For detailed care instructions by upholstery type, refer to the Humanscale Care Guide.

  • Frame, Base & Components

    Clean metal and plastic components with a soft, damp cloth and mild soap if needed. Dry thoroughly.

The chair has a minimalistic look but when you look into it you understand how much technology and how much work was, put into this chair to make it look so elegant and at the same time to be comfortable.

You'd never know that this sleek ergonomic office chair started its life in the sea.

The chair has the ergonomic virtues of the best office seating but its slim lines and optional aluminum trim give it a less corporate look, making it a strong candidate for the growing numbers of people looking to improve [their] home workspace.

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.

    Super simple to use

    Super simple to use. no knobs, no confusing adjustments. Clients immediately feel comfortable and I don’t have to worry about different body types.

    Love the clean look and ergonomic feel. Only thing is the seat is a little firmer than I expected. .

    Finally a conference chair

    Finally a conference chair that actually supports you instead of forcing everyone into a rigid posture. My team loves it and I love the understated design!

    Design is sleek and minimal

    The design is sleek and minimal. Didn't love the feel of the plastic on the bottom of the seat, though.

    We got a set

    We got a set of these for our boardroom and everyone has commented on how comfortable they are. Even after 3-hour meetings, no one is fidgeting or complaining about back aches. The leather feels really nice too.
