SAFECELL SIDE IMPACT PROTECTION
Surrounds your child in a deep protective shell designed to absorb crash forces and shield your child from debris.

3 RECLINE POSITIONS
Make it easy to find the proper angle for secure installation and your child's comfort.

The Marathon Convertible Car Seat is an excellent choice for getting your family where they need to go safely and comfortably. SafeCell Impact Protection surrounds your child in safety components that work together to protect well beyond the established federal safety standards. And Complete Side Impact Protection shields your little one in a deep protective shell designed to absorb crash forces and protect from debris.

A car seat works best when it provides the right fit so the Marathon comes with the Quick-Adjust, 10-Position Harness and 2-Position Buckle to keep up with your growing child. Installation is made simple with Easy-On / Easy-Off LATCH Connectors that lock into place with an audible click and are easily released with the push of a button. Plush Foam Padding provides premium comfort at every touch point and there are even 3 Recline Positions so your child can relax at the right angle.

The Marathon converts from a rear-facing position (for babies 5-40 lbs.) to a forward-facing position (for children 20-65 lbs.) to keep your child safe and you free from worry wherever the road may take you.

I recently purchased this convertible car seat for my 8 months old baby and as expected I am satisfied with the quality. My baby has been using this brand since he was born from the carrier to stroller and now to car seat. I am always impressed with the style, safety and comfort it brings. I am sure my baby is safe whenever his in his car seat or stroller.
Pros
  • Safety
  • Excellent quality
  • Excellent design
  • Style & comfort
Cons
  • A little bit pricey

Excellent Carseat Seat
January 4, 2018
My little one really likes this car seat. It is very comfortable and easy to clean. I really like that it has a steel frame and it is really solid feeling. Also the plastic is not weak feeling. I really like that it has side-impact protection. I have had many Britax car seats in the past and they are the only ones that I will buy. Very good quality for the money. You won't find another car seat that will protect your child as well.
Pros
  • Steel frame and flex bottom. Side-impact protection.
Cons
  • Car seat is pricey.

I love that the headrest automatically adjust the harness around the shoulders! This is perfect! The rubber pieces on the chest clip are a great addition! So worth the money!
