My Husband and I were looking for a great car seat for both our 1year and 3 year old. Safety 1st Alpha was one of the only car seats we looked at because it was side impact crash tested. I drive a 4 door small car so my children are by the car doors. I needed something something safe, reliable, comfortable, and most importanty affordable. My children love the car seats  and fall asleep alost everytime they are seated in them. The Alpha car seat is easy to adjust to the right size and comfort for my kids. The only negative thing I have to say about the car seat it that it is a little bit hard...
