A child seat (10) applicable to frames (100), in particular of the "book-like" foldable type, of baby strollers and comprising a support plane or seat plate (11), a backrest (12) and a pair of armrests (13a, 13b), wherein the backrest (12) is hinged to the seat plate (11) or to the armrests (13a, 13b) rotatably about a first axis (A) and the armrests (13a, 13b) are hinged to the seat plate (11) rotatably about a common second axis (B) parallel or coinciding with the first axis (A), the child seat (10) further comprising first locking means (14) for locking the rotation of the backrest (12) about the first axis (A) relatively to the member of the child seat (10) to which the backrest (12) is hinged, the first locking means (14) being movable between a locking position and an unlocking position of the rotation of the backrest (12) about the first axis (A), second locking means (15) for locking the rotation of the armrests (13a, 13b) about the second axis (B) relatively to the seat plate (11), the second locking means (15) being movable between a locking position and an unlocking position of the rotation of the armrests (13a, 13b) about the second axis (B), a pair of rods (20a, 20b) which articulate to each other the backrest (12) and the armrests (13a, 13b) and each of which has an end hinged to the backrest (12) rotatably about a common third axis (C) parallel to the first and to the second axis (A) and (B), the opposite end hinged to a respective armrest (13a, 13b) rotatably about a common fourth axis (D) parallel to the first and to the second axis (A) and (B) and comprises at least one pair of rod-like elements (21a, 22a; 21b, 22b) which are coupled to each other in an axially slidable manner, wherein the first locking means (14) are defined at the rods (20a, 20b) in order to lock and unlock the relative sliding of the respective rod-like elements (21a, 22a; 21b, 22b) and, thus, in order to respectively prevent and allow the relative rotation between the backrest (12) and the armrests (13a, 13b), and the second locking means (15) are defined between the armrests (13a, 13b) and the seat plate (11), wherein the seat plate (11), the backrest (12) and the armrests (13a, 13b) are articulated to each other in a "book-like" manner moveably between at least one open position of the seat (10), wherein the backrest (12) and the armrests (13a, 13b) are in raised position with respect to the seat plate (11), and, when the first locking means (14) and the second locking means (15) are in the respective unlocking position, a closed position of the seat (10), wherein the backrest (12) and the armrests (13a, 13b) are rotated forward one on the others in lowered position and abutted on the seat plate (11).
