A child seat (9-18 kg), also known as a Group 1 car seat, is designed for children aged approximately 9 months to 4 years. It provides enhanced protection, proper posture support, and secure harnessing to keep your child safe while traveling in a vehicle.
This guide explains why a child seat (9-18 kg) is essential, the different types, installation methods, and safety tips to help parents choose the best option.
✔ Prevents Serious Injuries – Reduces the risk of injury by up to 80% in accidents.
✔ Mandatory by Law – Most countries require children under 4 years to use a Group 1 car seat.
✔ Provides Comfort & Support – Designed to support a child's developing spine, neck, and head.
✔ Ensures Proper Restraint – Uses a 5-point harness or ISOFIX system for secure fastening.
Fact: Standard seat belts are not safe for small children as they sit too high and can cause serious injury in a crash.
There are two main types of Group 1 child seats, designed for different installation methods and comfort needs.

✔ Recommended for children up to 2-4 years.

Correct installation is crucial for safety. Follow these guidelines:
✔ Rear seat is the safest location for child seats.
✔ Avoid front-seat installation, especially with airbags.
✔ ISOFIX System – Latches directly into the car’s frame for maximum stability.
✔ Seatbelt Installation – Uses the car’s three-point seatbelt to secure the seat.
✔ The harness should be snug (you shouldn’t be able to pinch any slack).
✔ The chest clip should be at armpit level.
✔ For rear-facing: The straps should be at or below the shoulders.
✔ For forward-facing: The straps should be at or above the shoulders.
✔ The seat should not move more than 2.5 cm when pulled at the base.
✔ Check the harness fit each time before driving.
Pro Tip: 80% of car seats are installed incorrectly—double-check using a car seat safety check service in your area.

A child should stay in a 9-18 kg seat until they meet ALL of these conditions:
✔ They exceed the height or weight limit of the seat.
✔ They can sit upright without slouching for long trips.
✔ They are at least 4 years old (but preferably closer to 5-6).
Once they outgrow the 9-18 kg seat, the next step is a booster seat (18-36 kg).
