What to consider when choosing a car seat

If you’re choosing a car seat for your child, talk to our car seat advisors in-store. We’ll help you find the perfect match for your child and your vehicle. It’s important to consider your budget and the brands you prefer, but the main factors will be your child’s weight and height.


  • A child’s weight is the deciding factor when choosing an R44 car seat.
  • Car seats with a more specific weight range will ensure the best fit for your child.
  • Some car seats can be used from birth up to 36kg with adjustable features to fit your child’s changing needs.


  • A child’s height determines the suitability of R129 car seats.
  • If you choose an R44 seat, children travelling in rear-facing car seats must still have their height monitored to ensure their head is supported by the seat.
  • All children require a car seat until they reach 135cm in the UK, or 150cm in Ireland.


  • A child’s age is not the best measure for choosing a suitable car seat.
  • If you’re not sure of your child’s weight/height and they aren’t with you for measurement, we can use their age to make an estimate.

Why choose a rearward-facing car seat? It’s safer.

Extended rearward facing seats reduce the risk of injury in a head-on collision by more than 73% compared to a conventional forward-facing seat. In an impact, the force is distributed evenly over a larger area rather than being focused on baby’s neck.

Only move your child out of rearward-facing car seats when their head has crowned the top of the seat or they reach the maximum weight outlined by the manufacturer.

What exactly is iSize or R129?

i-Size (R129) is a European Safety regulation regarding car seats for children under 105cm in height (approx. 4 years). These seats are categorised by height and size rather than height and weight.

i-Size car seats are designed to keep newborns rearward-facing until they are at least 15 months old. These R129 car seats are installed using ISOFix and side impact tested as standard.

i-Size does not replace the current ECER44/04 standard.

Safety Tips

  • Check the safety label. It should feature an E mark and read 44/04 or R129.
  • Never buy a second-hand car seat. There will be no record of whether the seat was damaged in an accident.
  • Children under 3 years should not be kept in a car seat for over 2 hours.
  • Avoid putting your child in bulky clothing when travelling. If you can fit more than 2 fingers under the safety harness, it needs to be tightened.
  • To avoid buckle crunch, the belt buckle of the car seat should be positioned down the side of the seat, with only the straps touching the frame.

Some tech talk explained…


Attachment points in a car, providing a solid and permanent connection between car seat and car body. This is the safest, easiest and quickest way to fit a car seat correctly. We have a wide range of ISOFix compatible seats in every group.

Side impact protection

Deeper side wings for optimum protection in a side-on collision.

Top tether

When hooked and tightened to tether points in your car, a top tether helps keep the car seat from tipping forward in a crash.

Support leg

Extends to the vehicle floor for extra stability. The support leg should not rest on an under floor storage compartment in your car.


Straps that keep a child secured in the car seat in case of a crash. The safest harness is a 5-point harness that secures the child at the shoulders and hips, and buckles between the legs.
