I really like this car seat it's easy to install and use. We even carry our son in it up the stairs while he's sleeping! Very light weight and great price!

This is a great seat. We have it in our second car. It's reasonably priced and is all you really need.

Britax issued a recall order on one of their carseats today due to unsafe harness mechanism. Please go to their website and make sure the carseat you are using is not one of the models that was recalled.

We have two of these carseats, one in each of our vehicles. Have loved it since the day we installed it. Very comfortable for our 3 year old who is very tall for his age. We are expecting our 2nd child in June and I hope they don't change anything about these seats by the time the next baby needs one!!

I have this carseat in my car for my 21 month old Granddaughter when she is out with "Gabby". I feel comfortable that she is safe as we cruising along. Great product! I would purchase this again!

I work for a law firm that deals with wrecks. When I had my daughter I asked them about brands. Britax is one that they listed.

These are pricey, but luckily my mother in law bought ours for us. My little boy did love sitting in it, and I felt that he was protected. His head didn't slump over when he fell asleep, like it did in other car seats. The only complaint I have is that you aren't supposed to machine wash the material. Obviously toddlers are going to have accidents, and I don't really feel that hand washing it gets urine or stains out of it good enough. We did put it through the washer and let it air dry. The material looks worn now. I don't buy anything that I can't wash in the washing machine, so it would be nice if they made a cover that could be machine washed!

I have tons of knowledge about carseats and baby gear of all sorts since I spent many years demonstrating and selling it all. When it comes to carseats, in my expereince most people shopped by price and what looked good or what fabrics felt soft. In reality this is not going to help when it comes to a car crash and keeping your child safe. The truth is whats behind that fabric. The Britax is one of the best seatbelts I have ever come across. They are known for their use of the same shock absorbing styrofoam that is used in bicycle helmets in their seats. When looking at any carseat, pull back the fabric because whats between the plastic frame and you're child's head is what counts, not the soft fabric that is not made for such impacts. I love the Britax carseats but in reality I know they are not exactly budget friendly. The good news is that many companies are now using the same styrofoam, it's just a matter of looking for it. Forget the color and fabric comfort and pull it back next time you look at a carseat. If there is nothing but the plastic frame then there is nothing that will help absorb impact from effecting your child in an accident. Go for the Britax but if budget concerned, REALLY look at the carseats in the store and make sure that there is something behind that fabric to keep your child safe.

We put our eldest in this seat around 18 months and 3 years later, she isn't anywhere near the 40 pound limit. I can't imagine her sister will be out of hers until she's at least 5 either. They are easy to install, durable and safe. What else can you ask for?

A great carseat. For sure our favorite brand. We have used others, but definitely prefer this seat, and would recommend them to everyone!

The Britax carseat line is definitely the only line I would trust my child in. After reading all the reviews and safety on all car seats we started using Britax when my daughter was 3 and she is now 8. My son is now in a Britax and I would highly recommend this to anyone who wants the best carseat for their child's safety. We chose the Marathon because of the weight limit being so high. We wanted our children in carseats as long as possible, with the most safe as possible carseat. It is absolutely Worth EVERY penny.

My research for a convertible car seat started early since my infant was on the tall side. I had narrowed it down to the Roundabout and the Marathon. Since the baby had to sit facing the rear, I wanted a car seat that would fit in my car (Mercedes C- Class) and not disturb the front passenger seat. I purchased both the Roundabout and the Marathon so that I could test them out in my vehicle. After reading all the specs, the two car seats are practically identical in features with the exception of the weight limit. The Marathon goes up to 65 pounds while the Roundabout only goes up to 40 lbs. The marathon is on the larger side and worked out fine when it was installed facing forward, however it is impossible to use facing backwards. The back of the headrest butts up right against the front seat and you also have to move the front seat all the way forward. Anyone sitting in the front seat needs to be extremely short in order for this car seat to fit. If you are interested in this car seat, I highly recommend purchasing at a place that allows you to return it in the event that it doesn't fit. The car seat is very safe and highly recommended, however I would go with the Britax Roundabout. They are almost identical with features with the exception of the size. The roundabout only goes up to 40 lbs (as compared to 80 with the Marathon), however I believe a child would prefer a booster seat once they reach 40 lbs.

I love my Britax seats. I have had 2 of them and they are worth every penny.

LOVE this carseat!!! It's pricey, but worth every penny; I know my daughter is safer in it and that makes me suggest this to every new parent I meet. My daughter also seems to be more comfortable in it than the other brand seats used by my parents and in-laws.

WORTH EVERY DIME!!!! GREAT!!!!!
