Biboni Sofa
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.
