The Britax Marathon ClickTight Convertible Car Seat features the ClickTight Installation System, making installation as easy as buckling a seatbelt. SafeCell Impact Protection surrounds your little one in safety, and Side Impact Protection, formed by a deep energy-absorbing shell, shields your child from the most severe type of collision.
