Some of the unique features on the Britax Marathon include a five point polyester harness with no tangle polyester webbing, which is certainly standard on most baby car seats. It also features built in lock-offs for the car’s seat belts and a push button LATCH system with versa tether. This Britax Car Seat provides the most security in both forward and rear facing installations. Now, the Britax Convertible Car Seat has Expanded PolyStyrene to increase available shoulder width room. EPS foam also helps soften a blow to the head in collisions. Britax convertible car seats are equipped with their patented HUGS system. It is designed to better distribute webbing loads to reduce head movement and minimize the chance for the webbings edge to load on the child’s neck.
The Britax Marathon provides parents with an all around all-star car seat. However, it may be too large for some vehicles. For those looking for a smaller Britax Car Seat, the Britax Roundabout is a perfect choice. It is a little smaller than the Britax Marathon as it holds up to just 40 lbs.
