The Biboni Sofa welcomes the human form with puffy folds precisely placed to envelop and embrace the sitter.
It’s both soft and supportive, holding the body in a relaxed yet upright position.On one hand, the bulbous shape of the Biboni Sofa is lighthearted and welcoming.
On the other, its scalloped silhouette and bespoke tailoring give it a formality and timelessness akin to that of a Chesterfield sofa.

Meet The Designer
Tobia Scarpa
The son of the famous Italian architect Carlo Scarpa, Tobia Scarpa trained in Venice before launching his career as a as a designer of lamps, furniture, and glass objects. In the early 1960s, he began to design modern furniture based on the principles of Le Corbusier. He and his wife Afra, designed for several of the biggest names in Italian design including Cassina and Gavina SpA,which his father directed.
With the 1968 acquisition of Gavina, the Bastiano Lounge collection was introduced to the Knoll catalog. The simple, comfortable design worked well with modern and traditional interiors alike and was one the most successful products of that time period. Although the Bastiano Lounge is no longer in production, several designers cite it as a major influence, most often complementing the successful harmony of soft cushions and a hard exoskeleton. Also introduced were Scarpa’s Pigreco Armchair and Andre Table.

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.
