Best Booster Seat – Buyer’s Guide

The transition of Booster Seats:

A child who is transitioned successfully from a front-facing car seat to a harnessed high-back booster will feel secure enough to ride without a harness. If they are smaller this type of seat may provide a better seat belt fit.

Most no-back booster seats also race the child up so the seat belt fits them correctly. 

The newer kinds of no back boosters work a bit differently. They lower the seat belt to snuggly and comfortably fit across the child’s body.

If you are using a no-back booster the child must have support to at least the top of his or her ears from either the vehicle seat or the vehicle headrest for head and neck protection.

Most high back boosters seats may be converted to a no-back booster as well. In case of a side-impact collision, this type of protection the Flex impacts energy away from your large child. 

Side-Impact Safety:

There are no universal side-impact safety standards but manufacturers do have their own. Some car seats may incorporate energy management in the form of an internal Tru system to reduce the force a child feels in a collision.

To consider how the booster seat for the large child will fit in your vehicle and make sure it can be correctly installed following the vehicle and the car seat guidelines. If you are driving with more than one child you will want booster seats that are narrow enough to fit side-by-side or three across and your back seat. 

Furthermore, if you looking for a seat that can be used through more than one child choose one with a later expiry date. You can find that date in your car seat manual or on the car seat itself.

If your child is often reluctant to get into a vehicle consider a harnessed booster seat that looks like their favorite cartoon or movie character. In this way, car travel will be a lot more fun.
