Great seat!

I loved this car seat so much, I bought a second. The seat is easy to install (with the instructions read over for proper installation) and it seems quite comfortable for my 2 year old who weight about 30 lbs. she loves the cup holders that can stay on the seat even in the rear-facing position.

The best books for little ones

The number one reason I love this car seat is how important safety is for my granddaughter! It is heavy and includes every safety feature you could think of! The dual cups allow her to fit her snack cup and drink! It is super padded for her comfort too! It looks nice in my car! The slim design takes up less space which is important when needing two seats.
