Materials & Sustainability
-
Product Materials
Diffrient Lounge is constructed using die-cast aluminum, steel, engineered polymers, contoured seat cushion, and upholstery textile. Die-cast aluminum and steel form the structural frame and recline mechanism. Engineered polymers are used for components requiring flexibility and impact resistance.
-
Solid Wood Worksurface
Solid wood worksurfaces are crafted from natural hardwood, offering a premium material experience with unique grain patterns in every surface. Each worksurface showcases the natural variation and character of real wood while providing long-term durability.
Who It's For
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.
-
Wood
Wipe with a soft, slightly damp cloth and dry immediately — do not allow moisture to sit on the surface. For marks, use a furniture-grade cleaner suited to wood. Avoid abrasive pads and prolonged direct sunlight, which can affect the finish over time.
-
Frame, Base & Components
Clean metal and plastic components with a soft, damp cloth and mild soap if needed. Dry thoroughly.
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.
