great seat

 from Utah– Verified Buyer

I love this car seat. It is so easy to install and it is always so tight and secure. The only problem I have with this seat is that its hard for my kids to fall asleep in it because it doesnt lean back very far.

Best Car Seat

 from Fort Worth, TX– Verified Buyer

Love Britax and highly recommend their products, they make the best car seats! This style of car seat is great the only thing we are not crazy about it the padding that goes around the shoulder harness strap, it is not soft but rather rigid.

We have 4 grand kids and have bought only britax car seats. Very easy to install and kids are comfortable in it. We got the all gray and it looks and matches the other seat. Great reviews!

Love this Seat

 from Caldwell, TX– Verified Buyer

My son was so excited to receive this booster seat. I had him in a car seat up to his 6th birthday. I feel a child should be greatly protected and not just thrown in a seat because of age. I want my baby protected and this seat is perfect. Thank you!
