Boa Sofa
Made by Edra
The Boa is among the most recognized objects in contemporary furniture, a sofa that refuses every convention of the form. Designed by Fernando and Humberto Campana, its name and character emerge from its sinuous, coiled construction: more than 120 meters of velvet-covered tubing, hand-knotted by four craftsmen working in concert, with no structural frame to govern its final shape.
Inside each tube, breathable flexible polyurethane and a fill of goose feather create a surface that is both yielding and resilient. The piece invites every posture, sitting, reclining, curling inward, adapting to the body rather than prescribing to it. Each Boa is, in this sense, unrepeatable.
The Campana Brothers draw on Brazilian craft traditions and a deep material curiosity, transforming humble or unexpected materials into objects of cultural weight. The Boa is a clear expression of that sensibility: its strength comes entirely from knot and tension, its silhouette from accumulation rather than engineering. Edra's Forlì atelier produces each piece to order, with the result varying subtly from one to the next.

Frequently Asked Questions
How is the Edra Boa Sofa constructed without a frame?
The Boa achieves its structural integrity entirely through hand-knotting. Four craftsmen work in coordination to interweave over 120 meters of velvet-covered tubing, with the tension and density of the knots providing form and support in place of any internal armature.
What is the fill material inside the Boa's tubing?
Each tube is filled with a combination of flexible, breathable polyurethane and goose feather, producing a surface that is responsive and soft while retaining its characteristic woven silhouette over time.
Who are the Campana Brothers and what informs their design?
Fernando and Humberto Campana are Brazilian designers whose work is rooted in the material culture of São Paulo. Their practice reinterprets humble or unconventional materials through a rigorous craft lens, a dialogue between informality and precision that defines pieces like the Boa.
Is the Edra Boa Sofa available in different colors or sizes?
The Boa is produced by Edra as a made-to-order piece, with velvet covering available in a range of colorways. Because each sofa is assembled by hand, exact dimensions can vary slightly between pieces, which is inherent to its craft nature.
How should the Boa Sofa be cared for over time?
The velvet covering should be kept away from prolonged direct sunlight to preserve its depth of color. Routine care involves gentle brushing along the pile direction; because the piece is frameless, avoiding sustained compression in one area helps maintain the evenness of the knotted form.
