Ensure Your Child's Safety with Expert Car Seat Installation

Ensuring the safety of your child while on the road involves more than just buying a car seat; it requires correct installation to effectively protect your child in the event of an accident. To guarantee that your car seat is installed properly, it's highly recommended to consult with a certified Child Passenger Safety (CPS) technician.

These experts are trained to review and correct car seat installations, ensuring that your child's car seat is as safe as possible. To find a CPS technician in your area who can help you ensure your car seat is installed correctly, visit www.cpsac.org. This step is crucial for the safety and peace of mind for all parents and guardians.

With just a few movements of the wrist, the new Hercules Small special needs booster folds into a slim, easy-to-handle format. This not only simplifies assembly in the car, but also ensures that the seat can be easily transported and stored in a space-saving manner even in limited trunk capacity.

FOR YOUR CHILD‘S CONTINUED SAFETY

Although child restraint systems undergo testing and evaluation, it is possible that a child restraint could be recalled. In case of a recall, we can reach you only if we have your name and address, so please fill in the registration form to be on our recall list. In order to properly register your child restraint system, you will need to provide the model number, serial number and date of manufacture. This information can also be found on a white label located on the back of the child restraint system.
