Size guide
All our car seats/bases are compatible with i-Size car seat requirements. However, not every car seat may fit comfortably in vehicles designed for i-Size car seats.
Our fit assistant will guide you in determining if the car seat can be comfortably installed in your vehicle and assist in finding the optimal placement for the car seat.
What is i-Size
i-Size is a European standard for car seats that prioritizes safety and compatibility, focusing on a child's height instead of weight. It guarantees a near-universal fit across car models with secure and easy ISOFIX point installations.
Check your car's manual or look for the i-Size icon to confirm compatibility.
What is ISOFIX
ISOFIX provides a standardized, belt-free method for car seat installation, directly connecting to the vehicle’s chassis for enhanced stability and security. Verify your car's compatibility with ISOFIX anchor points before choosing a car seat.
