If you want to compare Britax Marathon G4, Pavilion G4, Advocate G4, and Boulevard G4 here is a quick comparison for you to learn all the differences between them.
Let’s start with Marathon G4 which is the most famous convertible seat of Britax for the last few years, it is also the best way to define differences of these three car seats for us.
A newer version is now available, you can read more about it here, or read reviews from parents by clicking the image below.
Marathon G4 models have all of the features that pavilion and advocate have except:
- True side impact protection type
- Click and Safe indicator feature
- Super thick chest pads
Please don’t get it wrong, Marathon also has similar features but not exactly the same, for example Marathon of course has side impact protection but this the inside the cushion. Advocate and Pavilion models have also have extra head protection.
Marathon has also a different version of super thick chest pads than other models but it is still %100, safe.
The Click&Safe indicator means that when you strapped the harness correctly you will hear a click sound, this feature is missing in Boulevard and Marathon.
When we compare G4 line of seats the one with all the feature is the Advocate G4 model, it has a bulky addition in the head area for more safety, this is the only difference between the Advocate and Pavilion.
So if you want to sort these car seat with ascending number of features we have this order ( basic to advanced):
Britax Marathon G4
Britax Boulevard G4
Britax Pavilion G4
Britax Advocate G4
