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

We have used this car seat for 9 months now, and it is top of the line! Very light and sleek, easy to clip in to base and stroller, and can even be used without the base which has been so helpful with travel! We love how cushioned it is with removable newborn padding and head/neck pillows on the straps to keep our little one’s head from drooping while car napping. It is also easy to adjust and fai MacKenzie C. · strolleria.com
