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.

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

the back rest is very lose overall is an ok product for the price but one thing is missing that I didn't look for hard enough. the actual booster seat does not have the bottom seat belts that click onto the vehicles seat so that the boosters seat does not slide around, would have liked for the this one to have had that plus I thought it was a mandatory thing for child seat period.
