Reviews on Britax Marathon Convertible Car Seat Onyx
"Best Car Seat: We have been extremely happy with our Britax Marathon. At first, it was tricky to put in the car. However, after the first time, it is fairly simple to get in and out of cars especially once forward facing. My daughter is in the 98% for height and the Britax accommodates her very well."

"I will never buy another car seat: This car seat is beyond perfection. I cannot relate to people who have any complaints to make. It takes about 2 seconds to install with the latch system. I sit in it and wiggle from side to side until it doesn't budge. Everything about it meets the needs of any other standard car seat, this one is just better quality overall. I will never buy another brand of car seats." -Read more
"LOVE IT: We are so happy with this purchase. We have a smaller car (corolla) and it still fits just fine. Our 8 month old son loves the seat too, which is most important! He seems very comfortable and falls asleep very easily. We like the recline on the seat versus some of the other convertables out there. It was pricey but turned out to be well worth the money as it seems like it will last and is so comfortable." -Read more
