Group 2/3 Car Seats (4-12 Years)

Group 2/3 Car Seats for Children Aged 4–12 Years

When your child outgrows their Group 1 seat, a Group 2/3 car seat keeps them safe, comfortable, and correctly restrained all the way through to 12 years old. Our curated range covers children weighing 15–36 kg, offering the perfect blend of safety, longevity, and everyday practicality.

Why Choose a Group 2/3 Car Seat?

  • Long-lasting value – one seat that grows with your child from around age 4 right through to 12
  • High-back booster protection – side wings and head restraints provide crucial side-impact protection
  • ISOFIX & belt-fit options – choose the installation method that suits your vehicle
  • Adjustable headrests & harnesses – grow-with-me features ensure a safe, snug fit at every stage
  • Breathable, washable fabrics – easy to keep clean on long journeys

Safety Standards You Can Trust

All seats in our Group 2/3 range meet current UK and EU safety regulations, including ECE R44/04 and the latest i-Size (R129) standards where applicable. Look for the approval label on every seat for complete peace of mind.

Finding the Right Seat

The best Group 2/3 seat depends on your child's height and weight, your car's ISOFIX points, and how often you travel. Our team is on hand to help — browse the range below or get in touch for personalised advice.

Frequently Asked Questions

A Group 2/3 car seat is designed for children weighing 15–36 kg, typically aged 4 to 12 years. Group 2 covers 15–25 kg and uses a high-back booster with a vehicle seatbelt, while Group 3 covers 22–36 kg and can be used as a backless booster. Many seats span both groups, offering excellent long-term value as your child grows.

Your child is ready to move to a Group 2/3 seat when they have outgrown their Group 1 seat — usually when they exceed the maximum weight limit (typically 18 kg) or their head rises above the top of the seat. Always check the manufacturer's guidelines and never rush the transition; a well-fitting Group 1 seat is always safer than moving up too early.

ISOFIX is not mandatory for Group 2/3 seats, but it is recommended where available. ISOFIX anchors the seat securely to your car's chassis, reducing the risk of incorrect installation. Belt-fit Group 2/3 seats are also safe when fitted correctly and are a great option for vehicles without ISOFIX points. Check your vehicle handbook to confirm compatibility before purchasing.
