I'd say about 3-6 but they have to be a certain height and weight so it's different w/ every kid.
Comment from Phatcharapimon : it depends on which types of booster seats; i.e. some may help safely transport "big kids" from 30-100 pounds, etc. (http://astore.Amazon.com/healthy-care-booster-seat-20/detail/B004GEC8LU)
You can ride in a booster seat when you're two years old. You have to stop at age 8.
In the UK it is 133cm tall or their 12th Birthday before they can stop using a booster seat.
It depends on your weight and height. On average it it roughly about the age on 4.
Usually you can start sitting without a booster seat at about the age of maybe 6 or 7. Also it can depend on your weight.
a child is permitted to use a booster seat instead of a carseat based on height and weight, not age. the correct weight is 40 pounds and over 38" tall.
there's really no preference on age, but 4'9" and 45 pounds is the most commonly accepted law
there is no age limit . the child must be 1.5 metres tall
10 years and less
5
in all states a child has to be 4foot nine to be out of a booster seat. they can be in a booster sear at any age.
the weight to sit in a booster seat is...40 pounds AND the age of 4 years, BUT preferably the child is longer.
A child must be at least 25 kilograms or nine years of age before being able to leave the booster seat
10 years
The age in which a child can stop using a car seat or booster seat varies from state to state. In Michigan, the child safety seat law says that a child under the age of eight years old must be in a safety seat unless they are taller than 4' 9.
The age that a child should use a car seat booster is when they are 2 years of age. Some kids need to use them a little bit earlier because weight and height has an effect on how earlier the kids need to use the booster seat.
there isnt an age, it depends on the hight of the child :)
A child that is age 8 or younger and weighs no more than 80 pounds can use a booster seat in New Jersey. Children over the age 8 must use a seat belt.
It is not age but pounds for a child seat. Check with your DMV, but I think it is over 40lb.
4 The answer is NOT based on age but on the height and weight of your child. If your child is over 40lbs he/she can transition to a booster seat with lap/ shoulder restraint.
a child can be at leaset 6 to 8 years of age it really doesnt depond on height or weight
No, regardless of the child's age, a booster seat should NEVER be used in the front seat. An airbag can kill a child in the front seat if they are not tall enough and heavy enough to properly take the impact of the air bag.
