Big Kid Sport Booster Car Seat is rated 4.9 out of 5 by 20.
Rated 5 out of 5 by from Awesome big kid booster The booster seat is stylish and easy to assemble. The cup holder feature is a bonus. I as the mother have no complaints about the seat. It met all of my expectations. It feels sturdy and secure when installed. I will tell you what my four and a half year old had to say. She loves it. She told me that it so much more comfortable than her traditional car seat she had been using. She also loves the fact that it elevates her so she can see out the window. Plus it has a cool pink design. I will need to purchase one more booster for our other vehicle and will be buying an Evenflo Big Kid Sport.

Rated 5 out of 5 by from Great Booster I received this booster seat from Evenflo to test for my oldest. opened the box one night when it was just the two of us home. His eyes grew big, he could not believe the colors. He loves them. He likes how red the front part is and the bottom plaid is great too. He says it's very padded and comfy to sit on. The Belt Positioner works so much better than any other one I have used before. It is a great seat and the price is great too. When driving, he does't fly around, he stays secure in his seat.

Rated 4 out of 5 by from Good seat no issues just seems cheaply made but you get what you pay for. I use it as a back up but have a high quality seat for every day use.

Rated 5 out of 5 by from Great booster seat! My five year old daughter loves, what she calls, her big girl car seat. It was easy to put together and is good quality. The padded cover feels comfortable and was easy to put on. Most important, it fits securely in our suv.

Rated 5 out of 5 by from Comfy car seat! I was able to review this product for free for my 7 year old son and he loves it! He says it's a lot more comfortable then his other car seat (which I noticed right away as well) I also really liked the design of it too! The red is something you don't see very often on the booster seats. The seat belt fits perfectly where it's supposed to and I feel like my son is secure while using it. I would strongly recommend this product to anyone!

Rated 4 out of 5 by from Stylish and Roomy My 8 year-old daughter loves the look of the Mindy booster seat and doesn't feel like a "kid" when in it. She complimented the size of it and loved the handy cup holders. It could possibly use a tad more padding but she didn't really complain overall, just mentioned the back of could stand to use more padding. Overall we are happy with this booster and the ease of having it to move in/out of vehircles.

Rated 5 out of 5 by from Great Booster Seat! I received this booster seat to test for my oldest son, and we both love it! He had been complaining that his old seat wasn't comfortable anymore, and he says that this one is great. I like that it sits up a little higher than his previous seat, and has more room for him to sit comfortably. The colors are great and it's very sturdy. I highly recommend!
