Meet The Designer
Piero Lissoni
Piero Lissoni began his career as a furniture designer after receiving his degree in architecture from the Politecnico di Milano. In 1986 he founded his own studio, which specialized in architecture, furniture, interiors, and graphic design. He produced a diverse portfolio that included designs for showrooms, yachts, private residences and hotels.
In 2004 Knoll introduced Lissoni’s Divina Lounge Collection, originally designed for his longtime client, Living Divina. Two years later, he and his studio’s design manager, Marc Krusin, co-designed the wa office system for Knoll International. With no predetermined connection points, the brilliantly simple design featured a patented 360 degree clip mechanism allowing any component to be attached to any workstation, on any side.
Know the brand
Knoll
An item becomes classic when it changes the history of its time and continues to be modern at any time. Knoll’s history came from the birth of the Modern Movement and its protagonists; the idea of innovation combined with tradition; and the capacity to create highly versatile pieces that meet personal tastes and age trends.
Knoll stands at the forefront of mid-century modern and modern classic design, shaping interiors with pieces that feel both iconic and enduring. From the sculptural Barcelona Chair to the innovative Wassily Chair, and modern staples like the Saarinen Tulip Table and Florence Knoll Sofa, each design reflects the brand’s commitment to clarity, proportion and lasting craftsmanship. For those who appreciate timeless furniture with a strong architectural presence, Knoll remains one of the most influential names in modern design.
