The new seat pads are horrible

The new side pads on the seat are horrible. They don’t let your kid move their thighs out of the way so when you buckle them in their thighs get pinched. I really hate this feature and so does our son.

Great Car Seat

I bought this car seat because it has a higher harness height than most others and can do rear facing to 50 lbs. My 6 month old is 21 lbs and 30 inches so having a car seat that can last longer for her was important, since I am assuming she will continue to trend big. The car seat feels study and safe. The only disappointing part is it is hard to tighten the harness. You have to do small, short jerks. I even had to read forums on how to tighten it because it is hard.

One 4 Life

I didn’t get any incentives or free products. I had to pay for my seat. I love that I theoretically won’t need another seat for the life of my child. However, this seat is not meant for newborns or infants. Recommend the youngest is 4-5 months when they can hold their head up themselves due to having to take baby in and out. There’s no easy way to lug this bad boy up stairs with your child still tethered to it and keeping it out of the heat is a no go. Once you have this thing in you should leave it.trust me… It’s bulky and isn’t the easiest when leveling the seat. The 5 point harness would be better in the crotch buckle had more cloth to cover the plastic so it doesn’t dig into baby skin or burn baby skin in the heat. And less weird flaps and folds when trying to adjust to height and weight of the baby too please. Make the outside seamless and the folds on the inside. I think that’s all. K thanks for coming to my unpaid and honest review.

One and Done

I chose Britax because 1: of high reviews regarding their safety standards, and 2: I wanted a car seat that would last my baby’s entire childhood. The seat has a steel frame and is adjustable throughput all stages of car seat needed sizes. (I don’t want to have to buy 2-3 car seats per kid and always have some unused one sitting around like clutter.) This is my second Britax for my second child and the first one has been simple to adjust for my first kids growth. Cleaning it is a bit much only because of the pain of taking everything off and on but it’s not not confusing to put back and it’s cleaned up like new each time I’ve had to strip the cloth portions off to toss in the washer. There are plenty of clear pictures and straightforward instructions on the car seat so you wouldn’t need to use the user manual to install or adjust it but the user manual is itself very straightforward to follow along with. If you are looking for a car seat you can carry around, get one of their different models. If you want to consciously avoid leaving your child in a car seat for too long then this will ensure they only stay in the seat while they’re in the car. (I just baby wear when I’m out so it works for me) If your priorities for a car seat are: Safety All in One (never have to get another) Ease of installation & adjustment Machine washable cloth portions Attractive design Then the All in One by Britax meets these specifications I’m happy with both of mine and I will keep using them as I expand my family.

Haven’t Used it Yet

This car seat is for a baby that’s not die until another 6 months so ya. Also I’m being made to include at least 128 characters so here is the rest of the review wasted on what you’re reading currently.

Loved 2024 version, new version uncomfortable

I purchased one of these car seats about 6 months ago for my car and loved it. It feels very safe and doesn't wiggle at all. Over Thanksgiving we purchased a second one for my husband's car. I was really confused to see that the model my husband received was slightly different than the one I purchased 6 months ago. This new version has an additional "positioning layer" that you can't remove. Thus my toddler sits higher and more forward in this new model. The problem with this is that even when routed through the most-forward slot (which doesn't seem correct for a 13 month old when this seat should last until he's 10 years old), the crotch buckle sits too low and it digs into his thighs when buckled. I have it routed through both the shell and the cushioning. There's no way to loosen the buckle at all. If I could remove the positioning layer, then it could sit a little bit higher above his thighs like the original model does, but there's nothing I can really do. Pretty disappointed.

The jury is out on this new model.

We need a 2nd carseat, but much to my dismay the original one for life is no longer in stock in NZ. Replaced with these slim versions. Not impressed, these look dirt cheap but are very costly and the colour choices available are dull and pretty awful. I was looking forward to getting the original in coolflow carbon as that was the best colour choice available in my country. However I am very aware now that the US get all the good colours like blue, purple, red, black with orange trim. Why is that? How come only the dud and neutral colour ranges are available in other countries? Pretty disappointing. Other carseat manufacturers distribute all their colour choices worldwide but Britax don't. Happy with the click tight system and the safety aspect but not happy with drab colours and this model in particular looking like a poor cousin of the original

Great Slim All In One Car Seat

We installed the Britax One4Life Slim All-In-One car seat in our F-150 extended cab truck. We have 3 children, only one of which can ride in a booster, so basically three car seats across. My two favorite features of this Britax car seat are the slim design and the way the across anchor belt can be stored within. I’ve never had a slim car seat before, but I can see the difference it makes. I also really liked the fabric design - which isn’t necessary, but an added bonus (got the mineral gray). The car seat was relatively easy to install, but I do think it requires reading the instructions thoroughly. The cup holders are optional, but installing them doesn’t take away from the slim design. My only critique of the car seat is the harness release. I feel like it is in a low position and it seemed I had to really push it to be able to loosen the harness, but maybe over time it will be a little easier. Overall, it’s a great car seat! Thanks to the Stellar Product Testing Panel for providing me with this car seat.
