Abstract: A multi-functional infant gym is provided that is readily configurable into different useful forms. First and second arch members are pivotally connected to each other, allowing the gym to be positioned as desired. Lockable hinges can facilitate the pivoting of the gym. In a fully extended position, the gym can be used as an activity arch. Toys can be releaseably engaged with the activity arch, allowing for infant interaction with the toys. The gym can also be pivoted to a partially retracted position providing an infant sleep surface or changing mat. A pad member can be releaseably engaged with the gym. In a collapsed position, the arch members are nested in relation to each other allowing for compact storage and transport of the gym. A cover can be installed to protect the gym while in the collapsed position.
