I’ve been using this car seat for our 2 year old since he was about 7 months and outgrew the KeyFit system. I love this car seat. Unfortunately it is bulky for rear facing - it didn’t fit comfortably (for a front seat passenger) in my husband’s Mazda6 but it is just fine in my Honda Accord and our RAV4, so a large sedan or SUV is preferable, most likely. This seat is super easy to install securely MelissaR327 · chiccoshop.com
