Comfy

I really like the buffers on the straps. For a newborn, I don't have to worry about the straps cutting into her neck plus it is kn extra cushion to keep her head from bobbly around.

Long lasting everyday car seat

[This review was collected as part of a promotion.] I received the Maxi Cosi Pria All in One Convertible Car Seat from the Stellar Product Testing Panel and I have been very happy with it overall. It feels safe, sturdy, well-made, and my son is genuinely comfortable in it. The comfort level made the transition from the infant car seat very simple. The fabrics are soft and cozy while also feeling supportive but not overly bulky. I really appreciate the all-in-one design because it's clear the adjustable design allows it to be used for a long time as my child grows. I love that I can use this for the next few years without having to switch out seats or obtaining a new car seat. Adjusting the harness and headrest to fit him was easy and getting a proper fit was not complicated at all. This makes me feel confident that adjusting it as my son grows will be just as simple. Installation wasn't difficult, but it did take a bit of time to get everything positioned correctly and tightened well, especially because the seat is on the heavier side. Once installed though, it felt very secure and sturdy which is the most important part to me. Overall, this car seat is comfortable and safe, which are my top two priorities when looking for a car seat for my son. It makes the transition from an infant seat simple and offers longevity as your child grows.

Max Coziness

[This review was collected as part of a promotion.] We have been using this car seat (forward facing) for a few weeks now and have been very impressed with it. I drive a minivan and it is installed on the outside second row with two other car seats. It had no problem fitting. I was able to install it easily and my daughter has been able to strap herself in with no problems. I have not heard any complaints from her about not being comfortable. I received the product through the Stellar Product Testing Panel!
