Britax Marathon Vs. Britax Frontier


“What is the difference between the Britax Marathon and the Britax Frontier?”

Are you wondering what the difference is between the Britax Marathon vs. the Britax Frontier for your child? Both car seats are rated highly by experts, and will last children for several years.

Here are some facts I have gathered to aid you in your car seat decision:

  • The harness slots of the Frontier are 1 1/2 – 2 inches higher than the slots of the Marathon, so your child will have more use and more room to grow in the Frontier. Most car seats are outgrown by children due to their height, rather than the seat’s weight limit.
  • The Marathon will allow you to keep your child in the rear-facing position until her weight is 35 lbs, which is the safer position. However, if you are debating between the Marathon and the Frontier, than I will assume that your child is already traveling in the forward facing position!
  • If your car does not have the Latch connectors (standard in vehicles since 2002), then the Frontier can be more of a tricky installation than the Marathon — which is a consideration if you’ll be moving it between vehicles regularly.
  • The Marathon sits up higher than the Frontier, which can make it easier for a short child to view the scenery out the window during your car travels.
  • Some parents report that the straps on the Frontier are simpler to adjust than those of the Marathon.
  • As a 5-point harness system, your child will fit into the Frontier for far longer than the Marathon; there is about 2 extra inches of shoulder height room in the Frontier. Not to mention that you’ll get even more use out of it when you convert it to a belt-positioning booster seat.
  • Changing the harness height is simpler on the Frontier than the Marathon — no re-threading required.
  • Parents reported that it was easier for their kids to climb into and out of the Frontier than the Marathon because it sits lower on the vehicle’s seat.
  • Although the Frontier weights about two pounds more than the Marathon, due to its shape, it is easier to carry than the Marathon, which is a consideration if you’ll be taking it on a plane or transferring it regularly between different cars.
