Συχνές Ερωτήσεις για Children’s Car Seats: ISOFIX & 360° Swivel Seats

To choose the right child car seat, consider your child’s age, height, and weight, as well as compatibility with your car. Check whether the seat uses ISOFIX, the vehicle seat belt, or a base, and look for features such as side-impact protection, adjustable headrest, reclining positions, and easy installation.

The right car seat group depends on your child’s stage of development. You can choose from infant car seats, 0-36 kg seats, 9-36 kg seats, 15-36 kg seats, and booster seats for older children. Always check the manufacturer’s height, weight, and age limits before buying.

ISOFIX is a car seat installation system that connects the child seat directly to special anchor points in the vehicle. It helps provide a stable fit and reduces the risk of incorrect installation, as long as both the car seat and the vehicle are compatible.

i-Size, also known as R129, is a newer European safety standard for child car seats. It focuses more on the child’s height, improved side-impact protection, and safer installation. Before choosing an i-Size car seat, check that it fits your child’s height and is compatible with your vehicle.

A child should use an appropriate child car seat or booster until the vehicle seat belt fits correctly. In Europe, children under 1.35 m must use a restraint system suitable for their size and weight. Always follow your country’s legal requirements and the car seat manufacturer’s instructions.

A booster car seat is designed for older children who have outgrown a harnessed car seat but are not yet tall enough for the adult seat belt to fit correctly. It raises the child so the vehicle seat belt sits properly across the shoulder and lap.

No, not all child car seats are compatible with all cars. Compatibility depends on the installation system, ISOFIX points, car seat size, vehicle seat shape, seat belt length, and available space. Always check the manufacturer’s compatibility list or instructions before buying.

Rear-facing travel is especially important for babies and young children during the early stages of development. Many car seats allow extended rear-facing use depending on the child’s height and weight. Always follow the specific limits and instructions of the car seat model.

Most child car seats have removable fabrics or covers that can be cleaned according to the manufacturer’s care instructions. The frame and harness can usually be wiped with a damp cloth and mild cleanser. Make sure all parts are completely dry before reassembling the seat.

Yes, at Koudounistra you can find baby and child car seats for different ages, heights, and weights. Choose from infant car seats, 0-36 kg car seats, 9-36 kg car seats, 15-36 kg car seats, booster seats, and car seat bases, depending on your child’s needs and your vehicle.
