Great Car seat for Bigger Children

Date of Review:  Mar 3, 2008
The Bottom Line: Great seat for any child! Holds 25lbs more than standard car seats.
Review: The Britax Marathon car seat is a great convertible car seat. It can hold an infant from 5lbs up to 33lbs in the rear facing position, and from 20lbs to 65lbs in the forward facing position. It is made to European safety standards, which are higher...

The Best Money I have ever spent (updated)

Date of Review:  May 11, 2008
The Bottom Line: This seat will last the average child until they are ready for a booster seat. Britax is the leader in quality car seats.
Review: I purchased this car seat for my daughter when she outgrew her Graco Snugride infant carrier in 2004. She outgrew that seat around 4 months! She has been in the Britax Marathon since and is now 4 years old. She weighs about 50lbs and still fits very...

When "Good" just isn't enough...

Date of Review:  Jun 15, 2009
The Bottom Line: Easy to use, safer than most and comfortable for the little one.
Review: I am infatuated with my son’s Britax car seat.  When I worked at Babies R Us (about 6 years ago) I learned just about everything I could learn about car seats, how they’re made, how seat A stacks up against seat B and the ratings and what you should...

Safty is worth the price!

Date of Review:  May 29, 2008
The Bottom Line: Great SAFE seat from rear facing infant to toddler of 65 pounds.
Review: We own 2 of the Marathons and 2 of the Regents! We moved our 4 year old into the Regent when baby came. The Regent is a little better for the bigger kids but you certainly don't have to change. We just chose to move her.

A solid car seat

Date of Review:  May 13, 2008
The Bottom Line: If you want a solid car seat that is easy to install and gives you 100% peace of mind, then this is the car seat for you.
Review: I purchased mine when my older son outgrew his "bucket car seat" I read quite a bit and talked to many friends. The most common statement was "it is a really good car seat, but you will pay for that fact" That statement couldn't be more accurate. I...

Best car seat ever! worth every penny!

Date of Review:  Jan 16, 2008
The Bottom Line: It is a great quality, durable, safe, stylish, comfortable car seat on the market. Most of all my son loves riding in it.
Review: This is my second car seat, I had recieved a graco car seat as ashower gift and it was junk! I purchased the Britax after doing tons and tons of research on diffent brands. The Marathon fits perfect in my scion xb, it is a good size car seat and...

Great for our peace of mind

Date of Review:  May 5, 2009
The Bottom Line: Love the seat. You should "test drive" to ensure that it fits your vehicle- RF needs lots of space and top tether anchor is necessary for FF install.
Review: Bought this seat with 20% off coupon at BRU to help defray exorbitant cost. We are really glad we spent the money.

Our tall infant son is very comfortable. The summer heat in NC will cause everyone to sweat, and this seat isn't the best...

Excellent Car Seat!

Date of Review:  Jul 1, 2008
The Bottom Line: I highly recommend this car seat for the safety and the excellent value.
Review: I bought this car seat for my daughter when she was just under a year old. She's now 5 years old and weighs 40 pounds and is 40" tall and she still fits in this seat. Last week we moved the harness to the highest level on the seat and my daughter...

Safest I could Find!

Date of Review:  Mar 28, 2008
The Bottom Line: The only car seat I will ever purchase for its safety and ease of use.
Review: We figured that of any item we bought for our children, this was the one where money would be no object when paying for safety. We researched many car seats before deciding upon the Britax Marathon. Consumer Reports ranked this the safest car seat...

NOT FOR CHILDREN OVER 40 LBS

Date of Review:  Apr 1, 2008
Review: We own two Britax Marathons, one for our daughter and one for our son. I did my research when my daughter was born in 2003, and this was the best car seat. One of the pros to it was that it stated that it could hold a child up to 65 lbs. My daughter...
