Among Edra’s most iconic collaborators are Fernando and Humberto Campana, the Brazilian design duo whose raw, emotive, and often provocative works have redefined the language of contemporary furniture. The Campana Brothers are known for turning unconventional materials—ranging from rope and stuffed animals to scrap metal and leather—into poetic, high-concept creations that blur the line between craft and contemporary art. Their work is deeply rooted in the cultural energy of Brazil: vibrant, layered, and defiantly unpolished. Yet when paired with Edra’s technical mastery, their designs transform into sophisticated, globally acclaimed icons of collectible design. The Grinza Armchair is a product of this alchemy—a design that marries the Campanas’ love of the imperfect and the organic with Edra’s devotion to precision engineering and tactile luxury.

This boundary-defying ethos is profoundly reflected in Grinza, Edra’s enigmatic low-back armchair that appears more draped sculpture than functional seating. With its softly sagging upholstery—crafted in either supple leather or ecological fur—Grinza becomes an ode to imperfection. The name itself, meaning "wrinkle" in Italian, hints at the piece’s defining characteristic: an unpredictable, unrepeatable surface that forms through a manual draping process impossible to replicate. No two Grinza chairs are alike, as each is shaped by the artisan’s hand and the material’s organic behavior. The wrinkling is not a flaw, but a feature—an intentional celebration of chance and tactility.

Underneath this sensual exterior lies a steel tubular frame, outfitted with a patented coupling mechanism that allows the armrests to respond with subtle pliability. This hidden innovation ensures that the tactile softness of Grinza is supported by ergonomic intelligence, another Edra signature. In many ways, Grinza is the physical embodiment of Edra’s design language: one that invites the eye, indulges the senses, and defies categorization. It is furniture with soul, born from the Campana Brothers’ radical imagination and Edra’s unwavering dedication to craftsmanship.
