The Marathon Convertible Car Seat is an excellent choice for getting your family where they need to go. SafeCell Impact Protection surrounds your child in safety components that work together to protect beyond the established federal safety standards. Complete Side Impact Protection shields your little one in a deep protective shell designed to absorb crash forces. The 10-position harness and 2-position buckle keep up with your growing child. Installation is made simple with easy on/off connectors that lock into place with a click and are released with the push of a button. Plush foam padding and 3 recline positions offer premium comfort at every touch point. The Marathon converts from a rear-facing position (for babies 5-40 lbs.) to a forward-facing position (for children 20-65 lbs.) to keep your child safe. Babies”R”Us Exclusive Ultimate Comfort Series includes Memory Foam in the seat and head restraint and a cup holder for drinks and snacks.
