  • CarSeat
Color: Desert Wonder - PureCosi
I bought this for my daughter she is 8 months old and weighs 15 pounds. This car seat has so much cushion protection around them and was super easy to install. The best part is the chest clip is a magnetic piece and super thick rather than the clips that can pinch them. It came packaged very nicely in plastic protection and my box was delivered in perfect shape! Very happy with my purchase. ... show more

  • 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

  • Not the best quality car seat.
Color: Desert Wonder - PureCosi
I’m not sure if I got unlucky with this car seat but I hate it and my daughter hates it. the harness is INSANELY hard to pull. the straps always tangle. when it’s 85 F outside and your baby is screaming, it’s not the best time to have to take everything you have to pull the buckles securely. it also wobbles. i’ve done it forward and rear facing and it’s not safe. I hate that it took me almost a year to get a new car seat but I have tried to fix all the harness problems and nothing seems to help. also the tan color gets really dirty and my toddler has never peed in it just snacks and I wash it every 3 months and stains don’t come out at all. It was really cute at first but now just looks embarrassing. ... show more

The best car seat on the market. Easy to install, soft and comfy for my kids, super easy to adjust and looks great in the car.

  • 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.

  • 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
