Perfect!I LOVE this car seat. It was easy to install and I never have to worry about getting another one. It seems super comfy for my baby, and also super secure. Very happy with the purchase.

Straps are very hard to loosenReally great car seat. Have purchased many Chicco products. The straps are really hard to loosen because the button is in an awkward place when the seat is facing backwards. Hopefully they will loosen up after some use. Still love the seat. So does my 8 month old granddaughter. Would recommend.

Spot onSo far, so great. Using at stage 2 and it's nearly perfect. The straps take a couple days to get used to as they're somewhat difficult to loosen until you get the hang of it. Now I appreciate how secure they feel. We use it in a compact SUV and have no trouble getting our 11 month old in and out. He seems super comfortable and thrilled with the upgrade from an infant car seat.

Saved my sons lifeThe next day after we installed this my partner got into an auto accident with a driver that did a hit and run and also caused my partner’s car to roll over. My son came out of it without any issues and didn’t cry either. God was truly watching over him and my family and I can also thank Chicco for providing a very safe car seat.

TerribleWe have purchased two of these with in the last year and a half. Both of them have fallen apart. The styrofoam padding on the side and head rest has fallen off. We tried to get the headrest fixed and we’re told that it was out of warranty. When you spend this kind of money on something it shouldn’t fall apart within two years. I now have to buy two more car seats for my two kids. I can guarantee I will not be buying a Chicco product. If zero stars was an option I would give it.

Easy to use!This car seat is the best, easy to use, fantastic fabric and will grow with my little one.
Can the vehicle seat belt cover that comes with this for use in high back booster mode also be used with other chicco high back boosters or is it only allowed specifically for this seat?

We bought our car seat while living in Taiwan. It did not come with a chest clip. Is it possible to buy a chest clip and add it to our current one?

I am having such a hard time loosening the straps for the harness in this seat. It's almost like the orange release button is defective or something? Does anyone else find this hard to do? There's like no slack at all....
