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.
