Top Amazon Reviews

🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.


The Maxi Cosi car seat is praised by many for its comfort, leading to happier and more relaxed car rides for children. Notable features include a magnetic chest clip, ease of installation, and the option to go "all in one" for a minimalistic and flame retardant free approach. While some users did complain about the bulk of the product, the general consensus remains that it's a worthwhile investment for children's comfort and safety during travel.

Pros

  • 👶 Extremely comfortable for babies; many reviewers shared that their previously fussy babies now sleep peacefully during car rides.
  • 🧲 Magnetic chest clip feature appreciated for its functionality and convenience.
  • 🔩 Easy to install, right out of the box, and easy to adjust.
  • 🔥 Option to choose an "all in one" model which is flame retardant free.

Cons

  • 💪 Some users found the straps harder to tighten compared to other car seat models.
  • 🗄️ The car seat's bulkiness was noted as a potential issue, particularly if needed to switch between multiple cars often.

Should I Buy It?

Yes. If you value the comfort of your child during car rides and have enough room to accommodate a slightly bulky car seat, the Maxi Cosi is an excellent choice. It's easy to install, offers a superior comfort level, and provides safety features such as a magnetic chest clip. The occasional challenge with tightening the straps seems to be outweighed by the many positive aspects of this car seat.


  • Purchased over the Nuna and have no regrets.
Color: Desert Wonder - PureCosi
Had been eyeing a Nuna (only car seat ever purchased up to this point) for a 2.5 year old toddler and decided on this instead. Extremely satisfied with this purchase. First, it’s about half the price. Second, as weird as it sounds… It’s a pretty car seat. It’s more roomy than the Nuna, fits a toddler’s body better (IMO) and can easily face forward when ready. Had a minor issue and Customer Service was beyond attentive and responsive. Looking at Maxi Cosi car seats exclusively in the future. ... show more

Nothing but smiles . This car seat is great material , durable, and fits perfectly in the car . I’m kinda upset I didn’t get this one sooner !

  • 10 Month Old Loves It!
Color: Desert Wonder - PureCosi
We bought this after buying the Maxi Cosi infant car seat and stroller bundle. I love it because it grows with the baby. I’ve been hesitant with both Maxi Cosi buys because of some bad reviews but they are so easy to use, come in great shape, come with lots of manuals, and are super cute and match my aesthetic. This car seat is not that heavy, super easy to move (we move it from one vehicle to another often), and even fits in my tiny VW. My baby loves all the room to wiggle his legs and loves his cup holders haha (he’s 10 months). Great buy! I thought about getting the 180 or 360 version of this which would be cool but this one works just fine!! ... show more

  • No more tears!!! My baby sleeps in the car!!!
We Love this seat. I was a skeptical because my baby, a year old had not slept on a ride in the car, only cried almost every single minute of the car ride. Now we’ve had this seat a few days shy of a month. Since day one, THE VERY FIRST ride in this seat and she slept in the car, no fussing, not a tear shed. Every single ride since she has fallen asleep, no fussing, just babbling and comfortable…and that’s even with it being a hotttt summer in Minnesota, no air conditioning in the car as it just went out and not an easy fix/needs replacing. Baby is still happy!! And I’m so happy I bought this seat. I bought a color that was a little less expensive in the selection but in the car seat brand selection this one was a little pricier… I am glad I gave it a try as the return window with this company allowed for a good run to see how it performed. We will be keeping this seat and would re-purchase again and again. This is my third child, each child has hated the car. Now I think it was the issue of the sear as the problem and not the actual riding in the car. Also, we are still rear facing so it wasn’t the fact that baby had been turned forward, as to the fix in crying spells. I have two boys and a girl now… they all hated the car. They all have been nursed exclusively and attached to mama so, I thought that had something to do with it but now I feel like the comfort in this Maxi Cosi car seat must be like mama’s arms or even being held in the carrier/similar feel. The straps are just better placement around the shoulder and thigh. The head rest holds well while little one is riding/resting. The magnetic chest clip is superior!! The way the shoulder straps hold up and the way they are formed and how it lays on the collar/chest is way more comfortable for baby. She literally smiles and chats when I say “let’s go on a car ride!” And she happily loads in while I clip the straps in place. It’s really amazing. I don’t leave reviews for products purchased ever but I felt led to do this one with other struggling parents in mind. It really is almost too good to be true but I’ll gladly take it!! Life is better with this seat!! We actually love the blue color too!! Looks so nice and worth the price!! Last note is that it’s an easy seat to put in the car, easy to adjust headrest/back of the seat. Perfect right out of the box! I hope this helps someone! ... show more

  • Car Seat packaging and delivery service.
Color: Tetra Graphite
Purchased the car seat as a baby shower gift. The box arrived with a strip of clear tape above and below box. Original seat had been broken. Car seat appears to be intact however was not covered in plastic and the warranty card had been torn off. Car seat will not be given as a gift as this was clearly an open box return. Fortunately, I found the box before the downpour or the car seat would have been soaked. UPS left it out in the open instead of under the porch overhang. Will be returned. ... show more

  • Sturdy but bulky car seat
Color: Tetra Blue – PureCosi
A little confusing at first when trying to figure out the sizing and the buckles. This car seat is very sturdy but I think that it is a little big/bulky with small cupholders. I do love the magnetic buckle. That’s the biggest plus for me.

  • Super padded everywhere 🙂
Color: Tetra Blue – PureCosi
I like this car seat. I transitioned from a normal car seat to this for my 6 month old. It’s really padded near the head, back and where baby sits. Makes me feel good that my baby is protected. Very happy with car seat.
