Shopping for car seats is a daunting process that takes up time and a lot of energy. So why not find one seat that will last so you only have to do it once!? The PRIA Max All-in-One is built to grow with your child. And, most importantly, you can convert to new seat stages in mere seconds – because trust us, growth spurts really do happen overnight. 

The Pria Max All-in-One Convertible Car Seat is thoughtfully designed with features to simplify your life as you and your child journey together in years ahead. Pria Max is all about quick and easy, comfy and secure––a car seat specially made for your little one with conveniences parents love.

ClipQuik, the 1-handed, magnetic chest clip, and the Out-of-the-Way spring-assist harness holders make putting your child in and taking them out of their car seat easier than ever. And when they grow overnight, QuikFit, the 1-handed, integrated headrest and harness system, easily raises for the proper, comfortable fit. 

Bottom line? The PRIA’s here for the long haul.

  • Fabrics are all machine washable and dryer safe. Wipe plastic, vinyl, and metal parts with a damp sponge or cloth. The harness system should be cleaned with mild soap and water. Wipe the outside of the buckle with a damp cloth. Do not lubricate the buckle or immerse in water. Do not use bleach or harsh chemicals on your car seat and do not dry clean. Use of cleaning agents such as these can damage your car seat and cause deterioration of the materials.

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.
