An assembled pad includes multiple assembled mats connected to one another to define at least one cavity for receiving at least one subject matter. Each assembled mat is made of EVA and includes at least one tenon laterally extending therefrom and at least one mortise laterally defined to receive a corresponding one of the tenons of a corresponding one of adjacent assembled mats. The assembled pad has an undulated top surface for providing an excitation to an infant child who plays on the assembled floor. Each assembled mat has an irregular shape and a connecting edges between two adjacent assembled mats, and the subject matter and the assembled mats are flushed on each other for a smooth touch. The subject matter is a three-dimensional model such that the assembled pad has a vivid vision.
