My understanding is that not all Sweet Cherry carseats (very few of them, in fact) are certified as crash tested. So I would not recommend to rely on them to save your child's life in case of car accident, unless you have confirmed that the one you purchased is certified by a specific government body with crash testing requirements for child carseats. I know of only one that was certified (under Europe's ECE R44) and it was a booster seat, not a 5-point harness seat.

If anyone has had a child in an uncertified carseat that survived a car accident, do share the brand and name of the carseat! Saving money is always awesome, as long as it also saves lives.
