Frequently Asked Questions
What is ISOFIX and why does it matter for pet car seats?
ISOFIX is a standardized vehicle anchor system that connects the car seat directly to the car's frame — not the seat belt. This creates a rigid, rattle-free connection that significantly reduces movement in a crash. The Maeve™ iso5X uses integrated ISOFIX latches for a tool-free, rock-solid install.
Is the Maeve™ iso5X crash-tested?
Yes. It is independently crash-tested to iso5X certification standards — the same rigorous testing protocol used for infant car seats.
Is the Maeve™ iso5X compatible with the Roscoe™ Trek Stroller?
Yes — the Maeve™ iso5X clicks directly onto the Roscoe™ Trek Stroller frame for seamless car-to-stroller transfers without disturbing your pet.
What size pet is the iso5X for?
The iso5X is designed for dogs and cats up to 11 lbs. For medium pets up to 22 lbs, choose the Maeve™ iso6X.
