Britax Marathon 70-G3 Convertible Car Seat Review and Demo

`` (

Hello my friends!  Can you believe it’s almost Thanksgiving?  We’re still talking gear, gear, gear on CloudMom these days.  I will be back soon doing more vlogs answering questions from viewers but for now, we’re putting up a lot of gear shows because I want to make sure to publish these while the products are still fresh.  Special thanks to Albee Baby for allowing us to move into their store and review all their lovely stuff!

Britax Marathon 70-G3Pin for later!

So the latest addition to my weekly featured videos on strollers and car seats is convertible car seats.  And today I’m back with another car seat review and demo.  We’re stepping out of the world of infant car seats now and I’m reviewing the Britax Marathon 70-G3 Convertible Car Seat!

Britax Marathon 70-G3

This is a popular option for many parents, including me since this is the convertible car seat we ourselves chose.  You’ll notice that there is a wonderful amount of cushioning for your baby and a secure five-point harness system (a must!). In the past, you’ve had to change positioning of the loops for these harness straps as your baby grew. Now, with the Britax, you can easily adjust the position of the loops by moving the entire insert up or down.  Another high-tech feature is that during an accident, the Britax Marathon will actually intelligently distribute the energy in the seat during impact.

For a Britax Marathon rear-facing installation, you’ll need to start off in the reclined position. With a few clicks, you’ll know that the latches are securely in place! You can also install this car seat using the car’s seatbelt. Remember, tight, tight, tight! Refer to my visuals and the owner’s manual for further instructions.

One last feature that people love about this car seat is its safe cell technology. With this, you can be sure that your car seat is completely stable during even the bumpiest of rides! This is such a wonderful, high-tech car seat and is pretty simple to use!

Please watch my video for my full review and demo, and don’t forget to consult your product manual.
