I bought and easily installed a red and black version of this seat about two weeks ago for my daughter. She just turned one and was outgrowing her infant seat. We received a different convertible car seat as a gift, but this one is much more comfortable and is more padded than the other . It appears to be very safe. It does not move at all once strapped into the car. It's a big seat and she almost appears lost in in, but she has the room she'll need to grow. It's a good seat for children over one year of age.

This is my second frontier 85. Purchased it for my 4 yr old who was getting too big for his Boulevard. He loves that he has the same seat as his big brother.
