The car seat is perfect in terms of how it fits my tall 2 year old. Very comfortable for him and how it reclines. It’s very sturdy. I feel comfortable with the buckling in all aspects.

  • RECOMMEND
Color: Sunrise Coral 2
My daughter hates car seats and she ended up wanting to sit in this one! It sits her high enough she can see out the window. The car seat itself is slim with a deep cup holder so drinks don’t spill, and best of all it’s super light so easy to move from car to car. My daughter is 4 and this car seat has held up wonderfully so far! Definitely worth the money!! ... show more

  • Great product
Color: Old Soul
Just what I needed! My kids loved them and the straps were perfect. I have a 5&6 year old and these car seats were not too bulky but they were very sturdy and had good cushion. Cup holders were a plus. Very cost effective. Love that it adapts to your child’s growth over time. I would definitely recommend. ... show more
