NG: Did quite a bit of research and this car seat has been great. It fits comfortably in our sedan. The straps are smooth to adjust and don’t get twisted. My toddler seems comfortable in the seat and it seems very secure. Great value too.

Lesley H: This is the 2nd seat I've bought as it's so narrow for 3 across. It is very heavy though

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

Zadi: Takes a bit if time to install the first time but easier going forward. Its big and rugged, almost to big but makes sense since its supposed to support child till they grow. Reccomended.

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.

LizLiz: Installed this rear-facing into my F-150 last night.

The instruction manual IS there and it’s located inside the carseat at the back in the upper left side, there is a small symbol showing a book on the seat cover and if you unbutton the cover you can access it easily and pull it out (see my photos).

I used the UAS strap to secure it but it definitely was not tight enough, seems to be common in my truck. But once I also attached the tether by following the instructions and looping it around the seat in fronts track, it appears to be tight enough now. I am going to double check it and if needed add the seatbelt as well. This is only the third car seat I’ve ever installed before so I’m not a complete expert.

My daughter hasn’t used it yet but I will update my review once we use it for a while. I bought this particular car seat because it looks simple and it doesn’t block her view much and it feels very comfortable just from me pressing on it. And it is supposedly good for extended rear-facing. It is also a nice looking car seat from a reputable brand.

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...
