Various embodiments of the present invention are directed to a children's play gym configured for being converted between different configurations providing unique functionalities. In certain embodiments, the convertible play gym is provided with one or more adaptable entertainer components including various entertainment features (e.g., lights and sound producing devices). In a first configuration adapted for infants, at least one of the entertainer components is suspended above the play gym's mat and configured for reacting to movement, sound, or other input provided by an infant child laying on the play gym's mat. In a second configuration adapted for toddlers, the suspended entertainer component may be detached from the play gym's support members and reconfigured as a children's entertainment table (e.g., by itself or as part of an assembly with other entertain components).
