An exceptional and highly architectural pair of mid-century modern cone-shaped lounge chairs (often referred to as bucket or basket chairs), dating from the 1950s. These pieces represent a defining milestone in postwar Italian organic rationalism, beautifully balancing industrial structural efficiency with high-level natural craftsmanship. The design features a radical geometric silhouette—an uncompromising, sweeping inverted cone that eliminates the traditional distinction between the seat and the backrest. The substantial outer perimeter is framed by thick, curved solid bamboo, which supports a magnificent and extraordinarily dense web of hand-woven natural rattan. This intricately woven wicker body creates a fluid, ergonomic cradle that offers unexpected comfort and a beautiful interplay of light and shadow thanks to its texture. From a formal standpoint, this bold conoid shape directly references the innovative research on basic geometric volumes pioneered in the mid-1950s by avant-garde figures such as the architect Roberto Mango, who extensively explored the intersection between traditional wickerwork and industrial steel rods. Here, the organic warmth of the basket is masterfully balanced by an ultra-minimalist, black-lacquered wrought-iron tripod base. The slender metal legs flare outward, emphasizing the seat's ethereal lightness and sculptural suspension. A rare and highly sophisticated statement pair for international mid-century or contemporary collections.
