Why it's a best pick:
The Britax Marathon costs a bit more than the Roundabout but is longer lasting because it's designed to be used rear-facing for infants up to 35 lbs and forward-facing for kids up to 65 lbs. This seat has an excellent safety record and provides enhanced comfort for your baby. It's very easy to use and unlike cheaper seats, the five-point harneses are very thick and wide and do not get tangled. Installation is a breeze as well.
