Best seat- worth the expense. Loved this car seat. Not just for the obvious safety factors, but my child NEVER fought getting into her car seat. Not once. I have to believe it was because the seat was amazingly comfortable to her! I highly recommend Britax.

I absolutely love this car seat. I have same brand at home. And its great.

I have nothing but positive things to say about this car seat and Britax in general. I spent weeks researching convertible car seats before purchasing our Britax Marathon. Our tall son (90th percentile) has always been comfortable in it, both forward and rear facing; the straps are easy to loosen/tighten and remain straight (no twisting); it's easy to adjust as my son grows; and it's a breeze to clean. We love it so much, we just purchased a second for our new baby. The seats are a bit of an investment, but the quality construction and peace of mind from a top rated product are priceless

I love my Britax Marathon. We started using it around 6 months old in the rear-facing position and transitioned to forward-facing, using until my child was ready to move up to the Britax Frontier Harness Booster. Not only was this seat easy to install and move from car to car, but it was also easy to travel with. The seat is also easy to take apart for cleaning purposes. I always felt as though my child was safe and secure in this seat.

I've been using a Britax seat for over a year now and couldn't be happier! It's really easy to adjust when the child grows, and it's easy to put the child in and take them out. it isn't easy I get he seat in and out of the car if you plan to share it between vehicles though.

We have loved Britax! All three of our kids grew up in them!!!

This is a favorite car seat in use for 3 of my grandchildren! They are roomy and comfortable and keep the kids safe. They fit nicely in the backseat and gives the kids ample leg room.

Love our britax marathon! We bought a safety first as a second carseat for my husbands car and hate it. Wish we would have spent the extra $$ and bought another marathon.

Very comfy and easy to remove the cover for clean up. Easy to unbuckle and switch cars.

We absolutely love our Britax! Our first child is currently using it, and providing no accidents, our second child will grow into it as well! This brand holds its value, and you can count on it to be safe, sturdy, and dependable! It surpasses safety features, and the brand speaks for itself. The cover is easy to remove, wash, and put back on. Plus, it maintains it's shape!

I am a HUGE fan of Britax. Right now I think we have 5 different Britax car seats and boosters all together. My son is using a marathon add the daily one in my car. He is 5! We have been using this seat since he was about 3 months. I have purchased 2 maybe 3 boosters and everyone he asks to go back to the "big seat", it is easy for him to see out of the SUVs windows and he can reach much further to help get things for the littler ones. This seat is a must!!!!

We have one of these for each of our vehicles and have been very happy with them. Our daughter is comfortable in the seat. We have used for a little under a year and the car seats are holding up well. Great buy!

Really nice car seat. Stayed put after installation and was not wiggly. Easy to clean.

This is the safest and best car seat on the market. If you don't like the cover you can buy a replacement or make one.

Britax is durable, solid, and safe. It's adjustments have allowed us to use it a long time. Highly recommended!
