A car seat for children (1) comprises a shell (2) provided with a cavity, and a seat (3) configured to receive a child and at least partially inserted in the cavity of the shell (2). The seat (3) comprises a backrest (5) and a seating (4). The backrest (5) is rotatably constrained to the shell (2) at a first hinge mechanism (5a). The seating (4) is rotatably constrained to the shell (2) at a second hinge mechanism (4a). The backrest (5) and the seating (4) are movable with respect to the shell (2) to switch the seat (3) between an extended position and a seated position. The backrest (5) and the seating (4) are at least in part overlapped at an overlapping zone (6), and the backrest (5) and the seating (4) are slidably constrained to each other at the overlapping zone (6) by movement means (6a) for switching the seat (3) between the extended position and the seated position.
