The Costela armchair, created by the 1950s design maestro Martin Eisler and reissued by Tacchini, is characterized by a solid walnut ribbed decoration that covers both the seat and the backrest. In a short time, the model has become a benchmark for elegant and informal design. The attention is drawn to the wooden construction with curved strips in which the backrest is located. Large cushions provide an optimal level of comfort, while buttons serve as an additional design element. Wooden slats combine the natural warmth of solid walnut with fabric or leather that can be used for upholstery. The outer frame and legs of the chair are made of metal. All elements are available in other finishes.
