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:

• 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!
