Description

This rare pair of Costela armchairs was designed by Martin Eisler, in collaboration with Carlo Hauner, and produced by Forma in Brazil during the 1950s—a pivotal period in the development of Brazilian modernism. Introduced in the early postwar years, the Costela (Portuguese for “rib”) became one of the most iconic seating designs of the era, celebrated for its expressive structure and sculptural comfort.

The design reflects Eisler’s architectural approach to furniture, merging European modernist principles with Brazil’s tradition of artisanal woodworking and abundant native hardwoods. The armchairs are constructed from rhythmically arranged rosewood slats, gently curved to cradle the body, connected by exposed metal rods and pins that emphasize both structure and craftsmanship. This combination of visible construction and organic form was central to Forma’s philosophy, which sought to elevate Brazilian furniture to an international modern standard.

The rosewood has been professionally restored and refinished, revealing its rich tonal variation and pronounced grain. The seat and back cushions have been newly upholstered in a soft bouclé fabric with a sheepskin-like texture, enhancing comfort while remaining sympathetic to the chair’s mid-century character. The slender, curved steel frame with short legs provides a light yet stable base, reinforcing the chair’s balanced proportions.

Highly sought after by collectors, Costela armchairs by Eisler and Hauner are considered foundational works of Brazilian modern design. Offered here as a matching pair; available individually upon request.
