We love this carseat. Baby is comfortable in it and will sleep or just hang out during car rides. The materials are plush and easy to remove for cleaning. We brought our babe home in this carseat and the infant insert was so great when he was tiny. I really like the adjustable head/straps feature too. Super easy and I feel like I make it just a little bigger every time I put my baby in. Ashley · strolleria.com

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
