Get the right answers to these questions:
The retailer should check that the seat is suitable for your child’s weight, height and age.
The retailer should check the seat manufacturer’s information.
The retailer should point out the official standard mark (ECE R44.04).
The retailer should go over them with you.
The retailer should know that rear-facing child restraints must not be fitted where there is an active frontal airbag. Forward-facing seats should not be in the deployment zone of the airbag. Please check with your car manufacturer for further information.
Try not to compromise. If the shop recommends the most appropriate restraint, even though it’s more expensive, ignore your bargain-hunting instinct.
If you buy a child seat online or from an 'order-and-collect' store, be certain it fits your child and any vehicle in which it will be used. Seek expert advice when fitting. Some local authorities offer a free child seat fitting service.
