Eight “MT 552” Rosewood Dining Chairs, Geraldo de Barros for Unilabor, 1950s

Among the defining achievements of early Brazilian Modernism, the MT 552 dining chair by Geraldo de Barros embodies a rare convergence of artistic rigor, industrial innovation, and architectural restraint. Designed during the formative years of Unilabor in the 1950s, this exceptional set of eight represents one of the most celebrated dining chair models produced by the pioneering cooperative—an enduring symbol of Brazilian design at its most intellectually ambitious.

Executed in richly figured solid Brazilian rosewood (jacarandá) with finely hand-woven natural cane seats and backrests, the MT 552 achieves an extraordinary balance between visual lightness and structural confidence. Every element has been reduced to its essential purpose: slender rectilinear legs, crisp geometric transitions, and an elegantly restrained silhouette that allows the natural beauty of the rosewood to take center stage. The result is a chair that feels simultaneously architectural, sculptural, and remarkably comfortable.

The defining characteristic of the model is its subtly curved caned backrest—a gentle ergonomic sweep that follows the natural contour of the human spine. Rather than relying on ornament, de Barros employed refined geometry and precise craftsmanship to create comfort through proportion alone. This restrained curvature gives the chair a distinctive identity while preserving the disciplined rationalism that became synonymous with Unilabor's design philosophy.

Unlike many surviving examples, this complete set has benefited from a thoughtful professional restoration that respects the integrity of the original design. The rosewood frames have been carefully reinforced where necessary and refinished to reveal the remarkable depth, movement, and tonal variation of the timber while preserving its character and patina. Both the seats and backrests feature newly hand-woven natural cane, executed using the original six-way weave pattern and traditional techniques employed during the 1950s. The restoration restores the chairs to their intended appearance while ensuring decades of continued use.

Founded in São Paulo in 1954, Unilabor occupies a singular position in the history of Brazilian design. Conceived as one of the country's first worker-owned furniture cooperatives, it united progressive social ideals with uncompromising modernist aesthetics. Under the artistic direction of Geraldo de Barros—already internationally recognized as a pioneer of Concrete Art and experimental photography—the workshop developed furniture that rejected excess in favor of clarity, honesty of materials, and intelligent construction. Today, original Unilabor pieces are increasingly sought after by collectors, museums, and institutions for both their historical importance and timeless design language.

Geraldo de Barros remains one of the most influential figures in twentieth-century Brazilian culture. His work bridged fine art, industrial design, and architecture, helping define the visual language of postwar Brazilian Modernism alongside the country's leading architects and designers. The MT 552 perfectly encapsulates his philosophy: furniture conceived not as decoration, but as an expression of rational design, craftsmanship, and everyday functionality elevated to an art form.

Offered as a complete set of eight chairs, this ensemble presents an increasingly rare opportunity to acquire one of the landmark dining models of Brazilian Modernism in a cohesive, fully matched grouping. Their restrained elegance allows them to complement interiors ranging from historically significant modernist residences to refined contemporary environments, where their sculptural profiles and richly figured rosewood continue to feel remarkably current more than seventy years after their introduction.

The model is documented in Unilabor: Desenho Industrial, Arte Moderna e Autogestão Operária by Mauro Claro (Editora Senac São Paulo, 2004), further reinforcing its significance within the canon of Brazilian design.

An outstanding acquisition for discerning collectors of Brazilian Modern furniture, Geraldo de Barros, Unilabor, and museum-quality twentieth-century design, this rare set exemplifies the enduring sophistication, craftsmanship, and historical importance that have made early Brazilian Modernism one of the most desirable fields in the international design market. | Depth: 17 in
