Frequently Asked Questions (FAQs)
1. Do all car seats fit the same base?
Are All Car Seat Bases Universal? No, not all car seat bases are universal. When choosing a car seat base, it is vital to check and double-check that the base is compatible with your car seat make and model.
2. Are bases required for car seats?
Typically, you don't need the base to properly use your car seat — it's just a convenience. To install without the base, just thread the seat belt through the grooves on the side of the seat and tighten in the same manner as above. It should look something like this (for American car seats).
3. Can you buy extra bases for car seats?
You can buy extra bases. If your little one will be a regular rider in more than one vehicle (your partner's car, or a caregiver's or grandparent's car), you can buy additional bases — which is much less expensive than having to buy a whole extra car seat.
4. Are car seats with bases safer?
Clearly it's preferred to use your infant car seat with the base, but if you're traveling with baby, it's much safer to use your seat without the base than to not use a car seat at all. Do ensure that your seat CAN actually be installed without a base.
