    • Always love Graco!
Color: Eloise 2.0
Love this car seat! It was very easy to assemble out of the box, just click the back into place and put into the car. It was so easy to buckle into the car as well when I’ve had some difficulty with other car seats in the past. It comes with not one, but two cupholders. Those saying they couldn’t figure that out didn’t read the directions at all (which you really probably should be doing with a car seat anyways). The top piece of the cupholder just snaps out, and you turn it around and put it back in. It’s a super cute color, and slimmer than a baby car seat. My 5 year old likes feeling like she is in a big girl seat but still has the harness on which I like. All the padding is machine washable. It’s lower to the seat than a typical car seat so my daughter can touch the floor of the car ... show more

This carseat is great for my small 3 yo who wants the independence to get in and put of her seat on her own. 🧡

    • Great deal for adjustable booster seat for tall kids!
Color: Eloise 2.0
My twin daughters that are now 8 years old are too tall for their Costco finale booster seat, so I ordered this Eloise color booster seat and I am very glad I did. I ordered one out of two to test out the quality and how easy it is to install. It comes with each side clip hooks that hold down the booster seat to clip to the back metals that are directly under each seats (for all types of cars); which ensures the safety of this booster seat. I like how you can just adjust the height of the back support by pressing down on the lever directly above the head to protect your kids. The height accommodates kids up to tween ages which is perfect for my very tall (for their age girls)! I love the mauve pink rose color option too. I’m definitely going to order a second one for my other daughter since she always gets up during trips and comes out of her booster seats. The adjustable 5-point harness will definitely prevent her from getting out of the booster seat. I received this in less than 48 hours! The quality is worth the price and value! Thanks ... show more

    • Highly Recommend
Color: Black
Perfect Fit for Our 5-Year-Old! We absolutely love this car seat for our 5-year-old! It gives him a more “grown-up” feel without sacrificing safety or comfort. The slim design is a huge plus—we can fit multiple seats across without any trouble. It’s clearly made to grow with him, so we won’t need to replace it anytime soon. The head support is very functional and provides great comfort on longer rides. We chose the black color, and surprisingly, it doesn’t get hot like we expected, even in the sun. The security straps are easy to buckle and adjust, which makes getting in and out a breeze. Highly recommend! ... show more
