Julie Lafortune: super, ce modèle de siège n’est pas très large, il est idéal lorsqu’on veut mettre 3 sièges sur la banquette arrière

Ome Ed: Great for a small car. I put 3 of these car seats in the back seat of my 2022 Nissan Versa.

Chun Wah Chau: We bought this because of the slim design, as we have two car seats, it was hard for us to have someone sit in the middle. Even tho there is no cup spaces, it is much more easier to get in and out to sit in the middle now. Recommended if you need the space.

The same as picture so elegant and the water doesn’t stay at the soap bar which i like I recommend it looking elegance in our bathroom loved it: I like how does it fit in our car we bought two of them for my kids and they’re both happy in it. And we’re having a baby soon hoping the company send one as a gift in this Christmas season 😅

Anonymous: I like how narrow the seat is, will definitely fit 3 across nearly any car. The back is very tall so when rear facing the front seats need to be pretty far forward. In my tesla model 3 I have to put the drivers seat pretty far forward and I think most vehicles will struggle with this as well when rear facing. If it's put in the center of the car so it can fit between the front seats it's pretty good. Would fit great for forward facing. I don't recommend this for newborn as it doesn't hold the head on the sides. Probably best for a baby closer to 1 year old because the lack of head support and also the harness padding doesn't fit very well on a baby younger than 1 year.

N. V. G.: Girls love them. Comfy and sturdy. They fit in our convertible mini with space between seats

J Engineer: There were 2 features I purchased this for. The narrow construction that allows for 3 carseats side by side. It took 2 of these and another narrow seat to fit forward facing in a Saturn ion. Second is the all in one. Won't need to buy another seat or booster.

If used rear facing, these take up more room than other seats. They are tall, plus the angle make it difficult to fit in a small car with a tall person in the front seat. Would not work for an infant in my Ion.

I also like that is very sturdy. There's lots of metal in the construction. Feels safer. The trade-off is that it's heavy. But that's not a concern unless moving it from car to car all the time.

Have only used as a forward facing carseat so far. But I like all the options that it can be used for. There are less expensive seats, but having to buy a rear facing, then forward, then a booster ads up. May save money in the long run if starting with just this one all-in-one.

On the other hand, the dedicated infant car seats that can detach are super handy for going into stores without unbuckling your baby. Something to consider.

Overall, highly recommend this seat.

Haley: I purchased this car seat when I didn’t have much back seat space. I was able to fit this car seat into my car unlike a lot of other car seats. I appreciate that it saves on space but still seems quite durable. It does not come with cup holders like most car seats these days, however, I was able to purchase a separate cup holder attachment which has worked great. The seat is easy to install, and my child is much more comfortable in this seat as opposed to some other leading competitor seats. I wish I had bought this seats for both cars!

Nic Rupert: I flew two trips with this and another seat. It is heavy for flights, but I managed, also fairly quick and easy to install in a plane seat. If flying with it again I would devise a way to lock it folded up and to carry it as a backpack. Usually it is installed in a full size truck and I like how it looks and is easy to get in and out of for my 4 almost 5 yr old. Full metal frame and latch design is not cheap so has me convinced it's a good safe choice. The last seat I'll need to buy I think.

Jim S: I got this for my youngest who sits in the middle with booster seats on each side for her brothers. It is narrower than the one it replaces and I really like the red color and design. It looks like a high quality car seat and feels premium. It looks great and fits great in my Range Rover Velar. Overall, I like it but there are a few things to consider:

PROS
1. Great looking design
2. Premium feel
3. Easy for my 4-year-old daughter to buckler herself
4. Narrow
5. Comfortable for my daughter

CONS
1. It's VERY heavy. If you have to take this seat out from time to time, that might be a concern. This is for my car but my wife would never go for a seat this heavy. It seems like it weighs twice as much as the older Maxi Cosi seat it replaces. If the weight of the seat is a concern, avoid this one.
2. There is nothing intuitive about installing this thing. I had to watch a YouTube video just to find the installation instructions. I'm not kidding - they are hidden in the back fabric and housing. Once you have the instructions, they are not much help. This illustrations are professionally drawn but hard to understand. Even getting the various straps out of...
