Defined by its continuous, enveloping curvature and segmented upholstery, the form reads as both architectural and sensuous, with a quiet fluidity that distinguishes it from more rigid mid-century typologies.

Examples of this model are not commonly encountered on the market, particularly with such clarity of line and proportion. Its rarity lies not only in limited production, but in the difficulty of preserving the integrity of its curved structure and upholstery over time—making well-executed examples increasingly scarce.

The sofa is upholstered in a deeply saturated plum mohair velvet, positioned between wine and aubergine. The dense, directional pile introduces a nuanced surface quality—shifting from deep burgundy to softened violet undertones as it responds to light and movement. This subtle tonal variation adds depth and visual movement, reinforcing the sculptural presence of the piece.

Beyond its formal qualities, the Concha is notably comfortable—designed with a low, generous seat and a naturally reclining back that follows the body’s contours. The segmented cushions provide both structure and softness, offering a supportive yet relaxed sit that encourages extended use without compromising its architectural clarity. It is a piece that performs equally as a visual anchor and as a highly livable seating element.

Raised on slender, tapered legs, the frame maintains a visual lightness that offsets the fullness of the upholstered volume—a balance central to Tenreiro’s design philosophy. The result is a composition that feels grounded yet elevated, intimate yet expansive.

At once rare, materially rich, and deeply considered in its ergonomics, the Concha sofa stands as a compelling example of mid-century Brazilian design at its most expressive—where craftsmanship, comfort, and sculptural form converge. See less
