G.B.
All the carseats are made to become boosters that say they can be used as boosters. You simply take out the straps and use the seat belt instead. You can see the grooves on the high sides where the seat belt goes through when it's strapped. This holds the seat belt across the chest and it won't slide up over the chin.
If you buy a forward facing car seat that is not a booster it won't have those grooves for the seat belt.
And if you don't remove the straps on the ones that turn into boosters the kiddo's sit on the buckles and straps and it hurts.
If anyone wants to argue this point then please go to this Britax link, it shows the forward facing infant car seat being transformed into a full out booster. They move the back up and then eventually remove the straps.
