HIRAY Sofa uses metal, a key material in Kartell's green catalog, shaped through the welded wire process. This process creates a functional product rich in emotion, designed by architects and designers Ludovica + Roberto Palomba for Kartell. Metal wires form the lightweight and well-defined structural parts of the collection. The collection includes a chair, chair with arms, bistro table, armchair, divan, and side table. These various articles come in white, Bordeaux, black, and green, offering diverse options for different interior styles.
