Abstract: A chair for babies or young infants is intended to be placed on the seat of a conventional chair and comprises a base of substantially square horizontal cross-section, defined at the top thereof by a seat surface. Side and back support parts are formed integrally with the base and the seat surface and extend upwardly from a respective one of three base sides and three edges of the seat surface. The upper edges of the side support parts have gently rounded cross-section, and means are provided for securing the infant's chair to the seat of a conventional chair. The infant's chair is provided with a detachable front and crutch support, which includes a cross-piece, which extends substantially parallel with the front edge of the seat surface, and an upstanding crutch-piece, which extends between the central regions of the cross-piece and the aforementioned front edge.
