“Costella” Armchair in Hardwood & Chenille, Unknown, 1950s

Inspired by the celebrated “Costela” (rib) lounge chair popularized by Martin Eisler, this example reflects the distinctive design language that made the model an icon of Brazilian modernism. The name derives from the series of curved wooden slats that wrap around the seat and back, forming a rib-like structure that supports and frames the generous cushions within.

The sculptural shell is executed in Brazilian hardwood, recently refinished to revive its depth and tonal richness while preserving the integrity of its existing form. The dark-stained wood contrasts with the voluminous upholstered cushions, whose tufted surface introduces softness and visual rhythm. Nestled within the curved wooden cradle, the cushions create a dynamic interplay between structural expression and relaxed comfort.

While closely related to Eisler’s renowned design, this chair cannot be definitively attributed to Martin Eisler. Notable variations from documented examples include the proportions of the metal base and legs, as well as the presence of nine wooden slats rather than the eight typically associated with authenticated Costela models. Furthermore, no surviving maker’s marks, labels, or accompanying documentation were found to support a firm attribution. As such, the chair is best understood as a period reproduction or interpretation of the Costela design.

Supported by a slender metal base with lightly splayed legs, the chair retains the visual lightness characteristic of the form despite its substantial presence. The balance between expressive woodwork, engineered support, and inviting upholstery reflects the enduring influence of mid-century Brazilian design and the widespread admiration for Eisler’s original concept.

Recently restored, the wood presents with renewed clarity and the upholstery remains in excellent condition. Sculptural yet deeply comfortable, this chair serves as a compelling example of the lasting legacy and continued reinterpretation of one of Brazil’s most recognizable modern furniture designs.
