Evenflo Triumph Advance Vs Britax Marathon


“What is the difference between the Britax Marathon vs. the Evenflo Triumph Advance?”

Both convertible car seats, the Evenflo Triumph Advance and the Britax Marathon are of similar sizes and offer protection for children of similar weight.

Here are some of the differences between these car seats to help you in your decision:

britax Marathon convertible car seat vs evenflo triumph advance convertible
  • The Britax Marathon is easier to install, which is a factor if you may have to regularly transfer your car seat between cars.
  • The Marathon car seat has built-in lock-offs, for easier installation, which replace the locking clip; the Triumph Advance convertible does not. If you normally install your car seat with the Latch installers, then this won’t matter to you.
  • The Triumph Advance convertible car seat is wider at the top, so if your child is broad-shouldered, it will probably be more comfortable.
  • The Triumph Advance car seat has 2 crotch strap positions, while the Britax Marathon has just one, although its length is adjustable.
  • The Marathon has harness covers and a belly bad, which the Triumph Advance does not. (Although harness covers can be purchased separately for just a few dollars.)
  • The Britax Marathon has the fear-facing tether-ability of the straps, which minimize crash forces – and the Triumph Advance does not have this feature. There is some debate, even among car seat technicians, if this tether-ability which reduces rebound is beneficial. Most technicians do say that if a car seat offers the rear facing tether-ability, then use it, but it need not be a major factor in buying a seat.
  • The Evenflo Triumph Advance offers an Infinite Slide harness system, whereas the Marathon has slot straps. This means that you can always ascertain that the harnesses are at a perfect height on the Triumph Advance.
  • The Britax Marathon has straps that are replaceable. Which means that one nasty episode of vomiting on the straps of the Evenflo Triumph Advance (the straps can be just sponge cleaned, not immersed) may mean looking for a new, fresh-smelling car seat.
  • The Triumph Advance’s harness goes a bit higher than the Marathon’s, so you will get that bit of extra height out of it. Most children outgrow their car seats by height rather than weight.
  • The Marathon will hold your child rear-facing until 33 lbs, while the Triumph Advance will hold a rear-facing child until 35 lbs.
  • Removing and replacing the car seat covers for washing is simple on both seats, although a tad easier on the Triumph Advance, since you don’t need to re-thread the harness, as you do on the Marathon.
  • If you will be placing 2 or more car seats side-by-side in the passenger row of your vehicle, then the Britax seats will fit better, as they are designed to ‘puzzle’ together next to each other. The Triumph Advance is a bit wider and more cumbersome when placed next to another car seat, and 3 of them will not work across one row of a vehicle, while 3 Britax seats often will fit in the same row. (Every vehicle is different; these are general guidelines gleaned from countless experiences by parents!)
  • Both car seats are rated highly by Consumer Reports and have lots of satisfied customers – either one is a good choice if it fits your child and vehicle. The majority of the differences between the car seats come down to personal preference, so it’s ultimately up to you which features prefer and find simpler to use – and if one car seat seems to fit your child better than the other one!

    I’m assuming this review as for an older model Marathon? The ew model doesn’t have slot straps, as far as I know.

  2. Sarah says:

    The information you have in this article about purchasing harness straps for the evenflo is bad information to give out! NOTHING should be added to a car seat after market! These aftermarket items were not included in the safety testing, therefor they may actually compromise the safety of your child!

    • HI Sarah,

      There are different opinions from the experts about adding padding to car seat straps. Some experts say that they are unsafe, as they were not tested. Other experts maintain that as long as the padding does not necessitate making the harness longer than the length you’d use without the padding, it is fine to use.

  3. Kristen says:

    The argument about strap covers not being tested is ridiculous. It’s no different than the clothes the child is wearing. Are you going to require every outfit be tested to make sure they don’t interfere with the seatbelt?

    • Thank you for your insight, Kristen! You’re right – should we require testing of each outfit a child wears? My kids have some thin dress shirts and other furry winter clothing!

  4. Heather says:

    Which of these seats would best fit into a compact car when in the rear facing position?

    • Ellen says:

      The front to back space of the Evenflo Triumphs is actually one of the smallest out there — but the Marathon also is in that range! It depends mostly on the angle at which it was installed. Both of these are great choices for compact cars.
