Great Product BUY IT!!! GREAT PRICE!!

Easy to put together and install. My daughter is very pleased with it. My mom got a similar one off amazon that cost a bit more which I told her if I had known she was buying one to get off Walmart. Hers came with an extra accessory for if the seat belt is to tight around the neck area you can use this strap to pull it back a bit. Wish this one came with it. I looked everywhere but didn't see one. My mom had gotten the same brand but just black and grey instead of pink and black. Other thank that we love this purchase and will recommend it to anyone else.

More cushion is necessary 100%!!

It's a really good car seat just needs more cushion on the seat.. why would you want your child to sit in this when traveling as your child's bottom will be so uncomfortable! I added so much more cushion to the seat. Please start putting cushion to the seat area! Thanks

Thanks for your review! We would like to express our sincerest apologies for the cushion's insufficient support for your needs. We greatly appreciate your perspective.

Booster seems safer than car seat, still uncomfy

I bought the car seat just for a quick one time use on Halloween night while my car was in the shop , and it did the job. But I would not recommend for a daily car seat. While it is VERY lightweight and very easy to install , the car seat itself just didn't seem stable enough to offer much protection for a child. And also the padding seems quite thin. Would definitely be uncomfortable for long rides or daily usage. Not bad for a spare or quick short term replacement though I guess. The booster seat function seems far more useful, and safe, than being used as a car seat.
