For most parents, choosing Britax is an easy decision. Choosing which Britax is another matter entirely. The Britax Marathon is a convertible seat that accommodates babies weighing 5 to 33 pounds in a rear-facing position, and children over 1 year old, weighing up to 65 pounds, in a forward-facing position.
We love that the seat sits high up on the base, giving your child a great view of the world whizzing by. This seat will last most children from birth until they declare, "Mom, I'm too big for a car seat." Because this is a large, deep seat, you may need to install it in the center position in smaller vehicles in order to leave enough room for the driver and front passenger to recline. Many cars do not have LATCH in the center seat, so a seat belt installation would be necessary in this case.
The Marathon's safety features include the patented Versa-Tether™, built-in lock-offs, LATCH system, and EPS foam. The 5-point harness has four different shoulder heights that adjust at the back of the seat. A button in front allows you to fine tune the straps' snugness, depending if your child is wearing a bulky coat on a short ride to school, or just their PJs for an overnight trip. The cover is removable and machine-washable, and the seat is aircraft-approved.

Had this seat for my middle child when it first came out about 8 years ago and loved it so much that we bough another for our youngest. 33 lb rear facing weight limit is great, nice high back keeps children from outgrowing it height wise too early. LATCH is sooo easy to use on this seat thanks to great attachments that only require a push of a button to adjust.
Easy to install, Safe, Easy to Adjust
When my baby outgrew the infant car seat, we bought a Marathon for each car, and we like them very much. The Marathon is very safe and very user-friendly. We put our Marathons in the center of the back seats (less because our cars are small and more because that's the safest spot), and our cars don't have LATCH in the center, but the seat belt installation was very straightforward and easy to learn.
My favorite feature of the Marathon is the Velcro on either side that holds the straps out of the way while you put baby in the seat. Ingenious!

We have this seat in the Cow pattern and love it. It is sooooo soft and comfy and my kids love ridding in it. It is also very easy to install and use. I did not give it five stars though because my kids outgrew it rear facing before I was ready to turn them forward facing (2 years)
