Customers say
Customers find the car seat comfortable with plenty of cushioning, particularly near the head, and appreciate its appearance, noting it matches their interior perfectly. Moreover, they consider it worth the money and value its safety features, with one customer reporting their 15-month-old was protected during an incident. However, the size receives mixed feedback – while some say it fits perfectly in small sedans, others find it too small. Additionally, installation experiences are mixed, with some finding it easy to install while others struggle with assembly. The build quality and overall quality also receive mixed reviews, with some customers describing it as well-made while others report it coming apart after washing.

10 Month Old Loves It!
We bought this after buying the Maxi Cosi infant car seat and stroller bundle. I love it because it grows with the baby. Iâve 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 (heâs 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!!

Super padded everywhere ð
I like this car seat. I transitioned from a normal car seat to this for my 6 month old. Itâs really padded near the head, back and where baby sits. Makes me feel good that my baby is protected. Very happy with car seat.

Stellar!
Finally our sweet baby is comfortable and sleeping peacefully on car rides! We had a Chico handheld car seat that he started to hate after about 1 month old- this is such a relief to all, especially his comfort levels with traveling. I love that it will suit him as he grows too

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 weâve 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 comfortableâ¦and thatâs 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 Iâm 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 wasnât 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 mamaâs 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 âletâs go on a car ride!â And she happily loads in while I clip the straps in place. Itâs really amazing. I donât 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 Iâll 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 itâs 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!

Car Seat packaging and delivery service.
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.

Best car seat!!!
This car seat is awesome! Knowing my grandbaby is protected so well is the best feeling ever. My daughter has an expensive brand car seat and I will say this car seat is better.
