I've used many car seats with my step-children and now my daughter. This evenflo car seat seems to be more comfortable than the other car seats I've used. Usually the girls try to fight to get out of them but not with the symphony lx all in one. My baby girl loves this seat and usually sleeps better in it than in her own bed. The seat it fairly bulky and we can hardly get it in the car with the other 2 seats but I personally see it as a plus because it makes me feel my daughter is safer than in a smaller not so sturdy seat. I absolutely love the ratchet strap tightener because I know that she is in the seat as tight as possible and isn't going anywhere. With other seats I was always worried if I pulled them tight enough and secured properly.
