AMAZING

LOVEEE THIS CARSEAT!!! We got it for my daughter's upgrade out of an infant seat and I love it, she loves it, the only thing I would change is I would add a shade to it… I had to buy window shades because the sun hits her in the face. Overall the car seat is comfortable and great quality though!

I had the same car seat before and we love it, because my child sometimes falls asleep in the car and his head is secure it don't bounce when we hit bumps. Last month I was in a bad car accident in which my car was totaled. My son was in the car in his car seat nothing happen to him no bruises nothing. We decided to buy him a new one exactly the same for my son's safety.

Great car seat, the only issue is that you need to put something under the front of the seat so your child's head doesn't hang down when they fall asleep. But would recommend
