I was sent this carseat complementary from bzz agent to try and review. I have to say that I love it! It's so lightweight and all the extra padding for newborns is the perfect touch. It hugs my little one and she looks so comfortable. Not to mention puts me at ease that she is safe and secure. The adjustable base allows for the perfect position that I have never been able to get with any other car Nikky · shop.doreljuvenile.com
