How are all the Britax Rear-Facing Infant Car Seats Different?
A Comparison Between the Britax B-Safe 35, Endeavours, B-Safe Ultra and the NEW Gen2 series.
Britax is a great company, as well as one of my favorites, and they always tend to stay on top of their game. In the past few years, they’ve phased out of some great seats (like the 35 Elite), however, they’ve introduced new ones too. Most recently, they launched the Gen2 series of Britax rear-facing infant car seats. It features the Gen2, Gen2 FlexFit+ as well as the Gen2 FlexFit. As a result, I think it’s safe to assume the “older” line will be discontinued and replaced with the Gen2’s.
There are TONS of similarities but also several changes in each one that help set them apart. I’ve compiled a few easy-to-navigate charts to help you see what the differences and similarities are so you can narrow down which Britax rear-facing infant seat is best for you and your family.

Thanks for this comparison. I believe the Endeavours comes with the ARB base as well
Yes it does!
Hi, Is the crotch strap on the Britax Oneife the same length as the other Britax convertible Car seats? We have the Britax Marathon convertible but the crotch strap seemed to short for my boys and dug into their chubby thighs. We ended up getting the Chicco Nextfit for our other car because the strap was longer. We have the Britax Frontier booster seat the and the crotch strap on that one is longer than the one on the Marathon convertible seat. I am interested in the One4Life if the crotch strap is longer or is able to be made longer as the child grows Thank you!
Hi Marlie! As far as I’m aware, they’re all the same size. However, the Britax convertible seats do have adjustable straps that allow for the straps to be shorter for newborns/infants, then lengthened for older children. If you look where the lower part of the strap attaches to the seat, (the attachment point closest to their little thighs), you’ll see that the fabric of the strap has a little loop. That loop will be hooked onto the inner loop for infants. You can detach the strap, and then re-attach it using the outer loop of fabric to lengthen the straps.
This is from the Britax manual (pg. 23)
