1. A child seat comprising:
an outer shell supporting an inner shell therein, the inner shell and the outer shell together defining a child protection region within the seat; and
an adjustment mechanism disposed between the inner shell and the outer shell defining a trajectory of movement for the inner shell relative to the outer shell;
wherein movement of the inner shell relative to the outer shell along the trajectory of movement adjusts a size and a shape of the child protection region of the seat to transition the seat between a compact configuration and an extended configuration;
wherein the adjustment mechanism comprises a latch having a pair of opposing latching pins mounted to the inner shell via a release lever, each latching pin constrained to travel within a respective extension track of a pair of opposing extension tracks of the outer shell in a first unlocked configuration;
wherein each of the pair of extension tracks comprises a peripheral wall defining the trajectory of movement between the inner shell and the outer shell and a plurality of corresponding locking apertures for receiving and retaining the latching pins in a second locked configuration.
