Carseat is butter soft and ultra comfortable
[This review was collected as part of a promotion.] I was given this car seat to try as part of the Stellar Product Testing Panel. This is the Kani 4 in 1. The materials are ultra soft like you would expect from Maxi Cosi. I bought the Maxi Cosi Pria 85 for my oldest child back in 2018, so this is a nice updated version we're using for my littlest addition. I love the slim design that fits my little sedan, even with another carseat in the back. It's roomy enough for them to use for years and years. One of my favorite parts of the carseat is the magnetic buckle closure. It takes a bit to get used to if you're not used to that kind of feature. I really can't say enough how soft the material is and it feels easy to clean. Another great feature is two cup holders, one we use for water and another we use for a cup of snacks. The crevaces in the carseat make it easy to vacuum out those said snacks. I love the black color which is sure to hide stains really well, unlike my other grey carseat. The buckle also feels very secure. The only drawback to this carseat that I can possibly see is that it's relatively heavy, but it's also feeling much sturdier than my other carseat. I'd feel comfortable bringing this on an airplane and have them handle it, unlike my other one from a different brand. The overall value is top notch right here. This is a carseat that is built to last for all ages. It goes without saying that the carseat manual is easy to read, so installation is a breeze, even for a first time parent. I am glad we have this!
All about the trim and sleek design
[This review was collected as part of a promotion.] This MaxiCosi is truly the raddest, most fashionable carseat I've ever come across. Its subtle leather-like trim is my favorite part about it—this carseat is definitely more for the style-conscious parent rather than the kid! The slim design is so helpful and gives my 3year old more than enough space to be comfortable. I am thrilled we'll be able to continue using it until the booster phase. If I could go back to when I first had my baby- I'd definitely go for this 4in 1 design- it makes the best sense financially and environmentally which are two pretty big factors for our family. It was super easy to install as most are. I was excited for the new magnetic clip style, but found it to be slightly tricky to undo! I think I need more time getting used to it. Buckling him in though is a breeze! I'm so grateful to have had the chance to receive this carseat on behalf of the Stellar Product Testing Panel. I would absolutely recommend the Kani!
Comfy Maxi Cosi Kani convertible car seat
[This review was collected as part of a promotion.] When I opened the car seat, the first thing I noticed was how comfortable and cushy the overall car seat was. Thanks to the Stellar Product Testing Panel for providing me with this car seat. To be honest, I was a little jealous my chair isn't as plush and luxurious! I love that the car is a convertible car seat and plan on using this from rear facing — currently my 8 month old is in it until she is forward facing. Before installing in the car I did attempt to see if my 5 year old son could use it but he maxed out the height. When I was trying to figure out how to install I noticed you can also extend the seat/leg area as well for further prolong use and comfort. I was bummed my car did not have the metal latches. My favorite feature was that the latches had its own designated latch ring holder so it does not clank and fly around the car and love that it makes the car organized, especially since we have so many other kid-related things in the car. I realized after taking the photos the car seat also comes with removable cup holders which we have installed. My 5 year old ended up playing with them when I opened the box hence not pictured! The installation was easy using the seat belt path when rear facing, latches if your car has them, and the additional tether once the kids are forward facing. The chest clip took a while to get use as it's a magnetic button as opposed to a slider function. After 2-3 times you remember to push then pull as opposed to push and slide. I would recommend this car seat as a primary or even when traveling since the install process is so easy and quick!
