At what age can my child use a car booster seat?
Safety booster seats are really meant to be used by children who have fully outgrown a safety seat with a full harness, so if you choose one that has a harness that goes to, for example, sixty or eighty pounds, you would then use the booster seat later if the child still did not fit into the safety belt properly. For most people, booster seats are used at about age four if the child weighs over forty pounds. That weight is related to the other products that they might be using and their level of certification for the harness system; not because a weight has anything to do with needing to use a booster seat. The fit of the belt is the issue, and the age of a child. We do not recommend using a booster for a child who is under three. There are some three- to four-year-olds who move into booster seats because, although they're under forty pounds, the strap slots in their seat with a full harness are now below their shoulders. They've outgrown that product, and the parent has not been able to (or has not chosen to) find a seat with a harness that is higher than their shoulder level. So, then for the three- to four-year-olds it is a kind of grey area; a parental choice area, as to whether to use a booster seat or not.
