Abstract
An amusement system for infants is provided which gives a player a special bodily sensation that cannot be experienced in daily life. The amusement system comprises: a main body (10) including a mattress (11) of a generally flat rectangular solid shape housed in a frame (13), and pressing means (17) for externally pressing the mattress (11); and an enclosure (20) surrounding the frame (13). The mattress (11) comprises a bag (12) formed of a transparent flexible urethane sheet, and a liquid component including differently colored water and oil filled in the bag (12). The pressing means (17) includes a driver (18) incorporating a hydraulic cylinder, and a press plate (19) connected to a piston rod of the hydraulic cylinder. The press plate (19) is pivoted by the operation of the hydraulic cylinder to press a side face of the mattress (11) from the outside toward the inside, whereby the upper surface of the mattress (11) is waved.
