Kids always find it challenging to stay still when they’re in the car. Even adults find long journeys tedious at times, so it’s only natural that kids get tired too! But this restlessness and playfulness in kids is a leading cause of car crash-related deaths worldwide. Luckily, car seats or child safety seats exist, and they’re the best way to keep your children protected from accidents. There are many types of ClickTight car seats. Still, the three most popular are the Britax Boulevard, Britax Advocate, and the Britax Marathon. So let’s compare Britax Advocate vs Boulevard vs Marathon and see which one would be the most suitable for you!
Britax Marathon ClickTight
On the more pocket-friendly end of the spectrum, we have the Britax Marathon, an excellent choice for a car seat.
- Like the Britax Advocate and Britax Boulevard, the Britax Marathon also has 7-reclining positions to fit your growing child.
- In addition, there is impact protection for the torso, head, and neck, much like other car seats, so your child is safe from all angles.
- A rear-facing installation also characterizes it much like the Britax Boulevard and Britax Advocate.
- It also features 14 settings that can be modified based on the child’s height.
- It has the same Click-Tight installation process that ensures an audible click to know that the seat is adjusted correctly.
- V-shaped straps (with double stitching) are also included.
- The double stitching absorbs the frontward motion of the child seat, preventing your child from experiencing impact. In addition, the car seat’s base has been developed to act as a shock absorber in so many ways. It also has a steel frame that is less prone to break or move in the event of an accident.
- The Britax Marathon lacks good padding, though. So if you want something more comfortable and ultra-padded for your children, then the Marathon is not the one for them. However, by many, this is considered sufficient padding at this low price.
The hard surfaces of this Car Seat are easy to clean since they are easily accessible.
