Unlike the previous reviewer of this seat I can't say enough about the benefits of rearfacing for as long as possible and then extended forward facing harness use.
I bought this seat for my 2 year old daughter who turns 3 in April. The seat is roomy and comfortable as well as extremly safe. And - safety is what is most important! Kudos to Safety First for making this seat have a min height of 34 inches for forward facing - what better way to discourage early forward facing than to make the seat just not do it! :)

The seat installed easily using the seat belts in my Ford E350. It only took me about 5 minutes and I got a really tight fit. I have a very large vehicle, so the size of the seat was not an issue for me. It is a large seat though, so you might want to try it in your vehicle first.
