Frequently Asked Questions

AI
Group 1 traditionally refers to weight-based categories (9-18kg), while i-Size (R129) is based on the child's height, which often provides a more accurate fit and more rigorous side-impact testing.
Installation depends on the seat type. ISOFIX seats lock directly into the vehicle's anchor points, while belted seats are secured using the car's three-point belt system, making them compatible with a wider range of older vehicles.
No, unless it is a combination seat designed for Group 0+ and Group 1. Standard Group 1 seats are designed for toddlers who can sit up independently and generally start from around 9 months or 15 months depending on the model.
