Frequently asked
What buyers want to know.
Self buckling in a HBB — can a kid work the seatbelt on the Cambria 2?r/CPST
Yes. Buyers report the latch system keeps the seat in place so the seatbelt doesn't slip behind it, which helps children buckle themselves. One owner found this especially useful for her 4- and 5-year-old daughters.
Booster for traverse — does the Cambria 2 fit in a Traverse or similar large SUV?
The Cambria 2 is designed as a booster for standard vehicles. Buyers have reported installation challenges in some cars because the wide base pushes against seatbelt holders, so fit depends on your specific vehicle's interior width.
What safety features does the Cambria 2 have?
Buyers and Consumer Reports rate the safety features highest, praising the side impact protection and noting it has far better belt fit than comparables. The latch connectors keep the seat secure during installation.
Is the Cambria 2 comfortable for kids?
Buyers rate comfort as a strong point. The seat also includes cup holders and snack holders on both sides, which owners describe as a major convenience.
What are the downsides of the Cambria 2?
The wide base can make seatbelt buckling difficult in narrower vehicle interiors. The light-colored cushion shows dirt and crumbs quickly and may require frequent cleaning to maintain its appearance.
High back booster rec for almost 5 year old with sturdy build — is the Cambria 2 a fit?r/CPST
The Cambria 2 is rated highly for comfort and fit by owners. One parent found it suitable for her 5-year-old, though checking your vehicle's interior width first is important because the base width can cause seatbelt routing issues in some cars.
