Product Materials
Liberty is constructed using die-cast aluminum, steel, engineered polymers, contoured seat cushion, multi-layer Duron arm pads, 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. The back features patented Form Sensing tri-panel fabric that takes on the exact shape of the sitter's back, providing a personalized fit and maximum adaptability.

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.
