Pair of “Costela” Armchairs in Brazilian Hardwood & Olive Mohair, by Martin Eisler, Brazil, 1956 — Lot 754

Description

Designed in 1953 by Martin Eisler (1913–1977), the Costela armchair stands among the most iconic expressions of Brazilian mid-century modernism—an exercise in structural clarity where material, form, and engineering converge with quiet precision. Produced initially by Móveis Artesanal and later by Forma S.A. Móveis e Objetos de Arte, the model reflects Eisler’s disciplined and deeply architectural approach to furniture design.

Its name—Costela (“rib”)—derives directly from its construction. A series of rhythmically spaced Brazilian hardwood slats arc outward from the seat, forming a sculptural enclosure that is at once structural and expressive. These curved elements generate a sense of tension and release, embracing the upholstered body while establishing a dynamic dialogue between linear rigor and organic curvature. The composition is anchored by a blackened steel base with subtly splayed legs, introducing a restrained industrial counterpoint to the warmth and density of the hardwood.

The hardwood frames have been professionally refinished to a satin-matte surface, revealing pronounced grain movement and tonal depth characteristic of early Brazilian production. The steel structure remains in original condition, preserving the authenticity and integrity of the piece.

Newly upholstered in a rich olive mohair velvet, the cushions present a plush, tufted profile with a soft, directional nap that enhances both depth and tactility. The upholstery sits in quiet contrast to the disciplined geometry of the frame, reinforcing the chair’s balance between comfort and structural articulation.

A seminal work within Eisler’s oeuvre, the Costela armchair embodies a uniquely Brazilian synthesis of European modernist principles and local material sensibility. Sculptural yet restrained, it remains one of the most enduring and recognizable seating forms of the period.

A beautifully restored and cohesively upholstered pair—an increasingly scarce offering within the market.
