When we bought this seat because we invested in a Recaro convertible 3 years ago and it was time to move up because we were expecting another child and wanted to use the convertible for her. At that time, it was one of the very few that was rated for side impacts. Recaro offered side impact testing ratings before it was required in the United States. Even with other brands coming out with similar seats now, I also like to think that bigger is better when coming to safety. This seat is VERY solid much unlike some of my friend's flimsy looking seats. Solid to me equals a safer seat. Yes, its heavy, but I hope that the reinforced frame of the seat will protect my precious cargo in case of a crash. I love the 5 point harness and that it converts into a seat belt using seat that still latches into the car so that the car seat does not become a missal in a crash. Also, this seat is super easy to install.
