WHEN IS A CHILD READY
TO TRANSITION TO A BOOSTER SEAT?
Many parents confuse the words “car seat” and “booster seat”. It 
is important to understand the dierence between a car seat 
and a booster seat. 
A car seat is a seat the child sits in and uses a 5-point harness as 
their restraint.
A booster seat is a seat the child sits on and uses the vehicle's 
seat belt as their restraint. 
This Viaggio Shuttle Plus 120 is a booster seat.
Booster seats are for kids who are too big for their car seat and 
too small to t properly in a seat belt. Booster seats help the 
child’s body t properly on the vehicle seat. Booster seats make 
the seat belt start and stay on the correct bony parts of the 
child's body.
 
It isn't a coincidence that boosters make kids taller. By raising the 
child up, boosters help the shoulder belt t properly between 
the shoulder and the neck. By raising the child up and giving the 
child a shorter seat pan, the child's knees can now bend at the 
edge of the booster. This makes kids much less likely to slouch. 
Slouching is dangerous as it puts the lap belt on the soft belly
