SafeCell Side Impact Protection

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

Impact Absorbing Base

Compresses to absorb crash energy and counteract forward movement keeping your child clear from the seat in front of them.                    

Quick-Adjust 10-Position Harness

Allows you to easily move the harness upward and buckle outward for a comfortable, secure fit as your child grows.

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.

Love It!

My son loves his new car seat. It is so comfy. It is super easy to adjust and very easy to loosen the harness when it's time to get out. I do wish it would recline just a little more so it wouldn't be so awkward when my son falls asleep.

Great all around, comfortable car seat

Purchased on sale for a great price, wasnt sure about the color? But it was more muted than the pictures. Which was a good thing for me. My daughter was using a handed down seat from her older brother and hated it! She would fight us every time we tried to buckle her in. Now with the new seat she climbs in herself!! Its so cushioned and comfy especially in the seat area. I don't mind the bright blue so much because she loves the chair which makes my life easier!

Best Uses

Cons
  • Recline is too deep, would have liked a midway recline option. Cup holder swivels and doesnâ
