A reconfigurable infant support structure includes a frame, a hanger arm movably coupled to the frame, and a seat movably coupled to the hanger arm. The hanger arm is placeable in a moving position and in a fixed position. The seat is positionable in a lowered position and in a raised position relative to the frame along the hanger arm. The seat is releasably securable in its raised position. The frame restricts the seat from being releasably secured in its raised position unless the hanger arm is in its fixed position. Conversely, the hanger arm can not be released from its fixed position unless the seat is in it lowered position.
