The True Fit is incredibly easy to install - takes less than five minutes and is tight as can be in our Toyota Matrix.
We love almost everything about the seat, but the harness tightening mechanism is awful. It is very hard to adjust when the seat is rear-facing. I hope that they fixed it with the new seats. My son adores it though. We sat him in all the seats they had at Target. Every other seat he squirmed to get out of, but he just melted in the True Fit.
