Good point lady muck!
I agree not uch boost so they cant see out of the window!
Would like to see more reviews and 'crash tests' before i put a child in one...
i like to keep them in high backed boster seats until tthye are at least around 6 as well...
despite all the guidelines on boosters it is proven that children under 22kg are MUCH safer in a high backed booster seat, and really shouldnt be on a booster only until they have reached this weight...
then on a booster from 22 - 36kg (or 150cm tall), whichever comes first!
