Do I have to use a base with my infant car seat?


No.  Safety 1st infant car seat bases are a convenience accessory, not a safety requirement for installation of the car seat. 

In some situations (i.e.: challenging vehicle seat profiles, minimal spacing between front/rear vehicle seats, and traveling on an airplane), installation without the base may improve the installation and fit/compatibility with your Safety 1st infant car seat.  Please see your model-specific car seat owner's manual for proper installation without the base.

Note:  This includes onBoard 35, onBoard 35 Air, onBoard 35 Air+, onBoard 35 Air 360, onBoard 35 LT, Light ‘N Comfy 22 Elite, and Light n Comfy Elite models.

Note: When installing car seat without the base, a vehicle belt installation is typically required.
