FEATURES

Knoll works alongside leading architects and designers known for their creativity and innovation—a legacy that continues with the Biboni Lounge Chair by Sharon Johnston and Mark Lee of Johnston Marklee. Echoing the language of their architectural practice, Biboni engages the body through an interplay of volumes, voids, and curves. Its rounded, expressive form carries a subtle sense of humor characteristic of Johnston Marklee’s work, while its scalloped silhouette shifts with the light, as changing shadows bring depth and detail to the surface.


CONSTRUCTION
  • Soft and supportive, the Biboni Lounge Chair holds the body in a relaxed position.
  • Its voluptuous folds are precisely placed to envelop and embrace the sitter.
  • Can be paired with the Biboni Ottoman (sold separately).
  • Especially striking when seen in the round—floating away from the perimeter.
  • Discreet inset feet add space between the sofa and floor, adding lightness to an otherwise substantial object.

FINISHES
  • Seat: wood structure, variable density flexible polyurethane padding, polyester fiber pre-covering
  • Backrests and Armrests: metal structure, flexible molded polyurethane padding
  • Upholstered in bi-elastic fabric (covers are not removable)
  • Feet: plastic slides

Los Angeles-based architectural firm Johnston Marklee was founded by Sharon Johnston and Mark Lee in 1998. Curved and scalloped forms are native to their work, which includes the Vault House in Oxnard, California; Pavilion of Six Views in Shanghai, China; and Dropbox Global Headquarters in San Francisco, California.

For architects Sharon Johnston and Mark Lee, putting furniture pieces together in a room is akin to putting buildings together to form a city. “Whenever we’re designing environments, it’s about the relationship between objects in the room, how you move in it, and occupy it,” they say. “Furniture is connected to the building as a part of the architecture.”

Their firm, Johnston Marklee, was founded in Los Angeles in 1998. Since then, they’ve designed a custom series of benches and tables to complement their architectural vision for the Menil Drawing Institute in Houston, Texas, as well as other built-ins for architectural commissions, including the Knoll Store in West Hollywood, California. Yet, their Biboni™ Sofa marks the first time the duo puts a piece of furniture into production. The design draws on Johnston and Lee’s ongoing investigations of the presence of forms in space, how space structures itself into volumes, voids, and curvatures, and how light and shadow can sculpt forms.

Johnston Marklee has completed a diverse portfolio of buildings in a career spanning almost three decades, including Vault House in Oxnard, California, Pavilion of Six Views in Shanghai, China, and Dropbox Global Headquarters in San Francisco, California. Their work can be found in the permanent collections of the Museum of Modern Art in New York, the Art Institute of Chicago, the Menil Collection, the San Francisco Museum of Modern Art, the Carnegie Museum of Art, and the Architecture Museum of TU Munich.
