Child Seats (Group 1)

9 to 18kg (approx 9 months - 4 years)

Features

Seats in this weight range commonly consist of a seat shell attached to a frame. The child is held into the seat by an integral five-point harness and the frame is usually attached to the car by using the adult seatbelts. There is though a growing number of booster type seats available i.e. with no obvious 'frame' that are used as booster seats for older children but to which a harness can be fitted, turning them into a child seat for this weight range – look for seats marked 'Group 1,2 and 3'

  • Look for a seat that's easy to adjust
    You'll be letting-out or tightening the harness every time you add or remove clothes from your child. Simply try to adjust the size on the display sample but bear in mind that it'll be harder with a child in the seat.
  • Many child seats have a built-in reclining facility
    This might cost more but can be useful, particularly for younger children who may sleep more often.

Fitting tips

Fitting the adult belts correctly around the frame and making adjustments so that the installation is tight takes time and effort. Compared to booster seats, this type of seat can be more difficult to transfer between cars.

  • Compatibility can be a problem
    Despite the fact that seats are generally approved for universal use, few if any can actually be fitted correctly in all seating positions in all cars. Check the manufacturer's application list and ask the retailer to demonstrate correct installation in your car. See our advice on compatibility.
  • Incorrect fitting is a common problem with child seats
    This is particularly true of two-way seats, which can be used both forward and rear facing. This is another good reason why you should ask the retailer to demonstrate how to fit the seat correctly. You should also read the fitting instructions carefully and keep them in a convenient place.

    Make sure that the adult belt passes through all of the correct belt-guides and that the buckle isn't bent or lying on the seat frame. Some seats offer an 'alternative belt route' to help you avoid contact between the buckle and frame.
  • Child seats must be fitted tightly and securely
    To ensure you give maximum protection to your child, place the seat in the car and kneel into it to compress the car seat cushion whilst pulling the adult seat belt as tight as possible. You should be able to get it so tight that if you try to rock the child seat from side-to-side or front-to-back the car too will rock.
  • Belts can work loose
    Make sure that you check the seat before every journey and retighten it if necessary.
  • Harnesses should lie flat on the child
    There should be no twists in the webbing and they should be comfortably tight. Place your hand flat on your child's chest and pull the harness up tight against it for the ideal adjustment.

Useful points to remember if you are thinking of buying second-hand.
