A baby safety car seat convertible into a rollable baby seat includes right and left pairs of front and rear legs, a locking arrangement, and wheels. The seat has an intermediate mode in which a first leg of each pair is in its operational position while a second leg of that pair is in a different intermediate position. The locking arrangement locks the first leg in its operational position to the seat's support portion while allowing movement of the second leg between intermediate and operational positions. Alternatively/additionally, when a first leg is in its operational position, a second leg is movable between its intermediate and operational position, and the locking arrangement locks the front and rear legs of each pair to each other during movement between storage and intermediate states, and unlocks the legs from each other to allow movement of the second leg between intermediate and operational positions.
