Child Seat Terminology

Have you ever wondered which seat your child actually needed? What the terminology really means? This page sets out to help clear up the confusion around child seats.

Infant Carrier - Child Seat - Booster Seat - Booster Cushion

Infant Carriers

Infant Carrier

Group 0 and 0+: For children up to 13kgs (from birth to approx 9-12 months)

A baby seat is rear-facing, and can be fitted to front or rear seats using the normal seat-belt or using ISOFIX fittings as per the manufacturers instructions.

A rear-facing child seat should never be fitted in a seat with an active airbag - if fitted to a seat with an airbag the airbag should be disabled (Consult your vehicle's user manual for instructions on this procedure). An active airbag could cause a serious or fatal injury in the event of an accident.

Carrycots with restraint straps do not provide the same level of protection of a purpose-built baby seat.


Child Seats

Child Seat

Group 1: For children 9kg to 19kg (approx 9 months to 4 years).

A child seat is a separate seat secured by a normal seat belt or ISOFIX system attachment points. The child is then restrained in the seat by the seat's own harness, which has been designed specifically to fit a child.

A good child seat should include a 'crotch strap', this will prevent a child from sliding forward out of the seat in the event of an accident.


Booster Seats

Booster Seat

Group 2: For children 15kgs and up (from approx four years).

Designed to place a child in the right position to use a full adult seat belt. Many booster seats are designed to be used where only an adult lap-and-diagonal belt is fitted, however some are designed for use where only a lap-belt is fitted.

A booster seat is like a booster cushion except it has a back, and may have protection for a child's head during a side impact - as with the Recaro Start seen on the right.


Booster Cushion

Group 3: For Children from 22kgs (from approx six years)

Unlike the booster seat the booster cushion is designed to be used only with the adult seat belt and is designed to raise a child into a comfortable position where an adult belt gives proper support in the correct places.

Adult belts are designed to work best for adults over 150cm (4'11") or taller. They are not designed for children. Although a booster cushion might be unpopular with your child it will elevate them to the correct position for the maximum protection from an adult belt.
