This highly flexible seat offers the highest level of safety and comfort from 4 to 12 years. Highback boosters protect your child in 3 ways: the seat shell provides head to hip protection for your child, especially in the event of a side impact; the upper and lower belt guides provide correct positioning of the seat belt; and the padded headrest provides safety and comfort for your child’s head and neck. The XP-PAD provides extra protection when your child is secured with a 3-point seat belt. It’s made from advanced shock absorbing foam and in the event of a frontal impact diverts up to 30 %* of the energy forces away from your child’s delicate neck, supporting the head and cushioning the chest when your child is restrained.
