Meet the coolest car seat in town, the Pria Chill with VentMax technology. 

The first-of-its-kind Pria Chill will help keep your little one comfy in their car seat. VentMax is an integrated automatic fan system with specially designed sensors that engage fans to circulate air when the temperature rises.

Special open-cell padding and soft, breathable mesh fabric allow air to circulate around your child (2 fans in the lumbar area, 1 in the headrest) to enhance airflow and comfort. You’ll know the VentMax fans are engaged when you see the automatic indicator light. The VentMax system is also water resistant (don’t worry about spills!), super quiet, and shuts off when the car power port does.

This is a seat that can grow with your child, transitioning from rear-facing infant car seat to forward-facing car seat, then on to belt-positioning booster seat, for kids from 4 lbs to 100 lbs!

CPS Techs

What is a CPS tech?

A CPS tech is a Certified Passenger Safety Technician. Our Cubby Moms who have certified as CPS techs are specially trained on how to properly install car seats and booster seats, ensuring they know everything there is to know about keeping children safe in vehicles.
Through required continuing education courses and hours of personal research and team training, our CPS techs are able to remain up to date on the latest technical information regarding child safety.
Question mark icon

How does a CPS tech get certified?

In order to become certified, each prospective tech must attend The National Child Passenger Safety Certification Training Program. After intensive classroom instruction, they must pass a variety of written tests, demonstrate their knowledge through hands-on skills assessments, and perform safety checks at a check-up event before becoming certified. They learn the ins and outs of car seat installation possibilities, installing car seats in different vehicles, harnessing methods, and more. The car seat and safety industry is constantly changing, so our CPS techs here at The Baby Cubby are an invaluable resource for parents purchasing a new car seat, or for ones who simply want someone to double check that their current car seat is properly installed.
