A bended board and four thin supports are all that is needed for the assembly of this modest piece, both chair and stool, of Japanese inspiration. Its small backrest, designed to be disassembled, allows its appearance, and therefore its nature, to be varied depending on whether it is intended to occupy waiting, meeting or recreational spaces. Designed to be repeated, the bevel and the curvature of its seat make it possible to form a wave by arranging them in continuity, finding an unexpected variation that nevertheless remains silent when the piece is arranged individually.
