The Play Gym is a play mat with activity arch that accompanies babies during their first year. The mat has five educational zones at the edges which can be kept closed or opened according to the baby’s age. The child, according to its developmental stage, can thus look at educational images, feel fabrics, grasp items or discover colours and noises, without exposure to too much stimulation at one time. A brochure informs parents about the developmental phases and provides play suggestions for each month of life.
