A child must meet every limit for the mode they use. The labels on your seat and its manual are the final word.

Cosco does not publish a width for this seat, so measure your back seat and compare it with the seat in a store before buying.
Rainbow, Grape.
When they differ, follow the manual and the labels on your seat.
No campaign in the current NHTSA child-restraint data names this model family, and I have not run a separate review for it. Check your seat’s model number and date of manufacture before use.
