I just wanted to point out that the headrest on the True Fit can only be removed if baby is less than 20 lbs. After 20 lbs, the headrest must be used whether it's for forward facing or rear facing. So, in your case, you could use a True Fit without the headrest until your baby reaches 20 lbs, but then have to put it on after. By then though, your baby will have enough head control to install the seat more upright, so it won't necessarily take up more space. I have a True Fit Premiere and I love it. It has a nice and tall shell so it will last a long time rear facing for my skinny kid. But if you have a heavier and/or stockier child, you might want to consider one of the seats that rear face to 40 lbs such as the Graco My Ride, Sunshine Kids Radian or Safety 1st Complete Air. If you have a small backseat area though, you might have trouble with a Radian rear facing as it takes up a lot of front to back space. In general though, with most convertibles, it takes about the same amount of space front to back as an infant seat since you can install them much more upright once baby gets older.
