The best booster seat for your child

  • ISOFIX and non-ISOFIX booster seats
  • High-backed and non-high-backed options
  • A breakdown of what ISOFIX is and how to find it

There are two kinds of booster seats: the more traditional seats your child sits on and you buckle them in and the high-backed option. Whatever you choose, it’s important to remember that your child should be in a car seat until they are 135cm tall or 12 years old, whichever comes first; this is legally required. It’s also important to note that it is recommended that your child should be rearward facing until they are four years old.

Child Seat Safety, independent advisors to the UK car seat industry, retail, government, emergency services and consumers, announced their latest research specifically analysing the direction of all car seats for children aged four and under. Out of 2,000 car seats that were surveyed, more than one in four (26%) children were found to rearward face whilst 74% travel forward-facing. 2% were found to be on unsuitable booster seats, 17% on high-back boosters and sadly, 1% were not restrained at all.

Many of us have our children forward-facing because it’s nice for them; they can see more, and if it stops the moaning from the backseat for a little bit longer, then it makes the journey less stressful. Choosing a car seat which is safe and secure while being comfortable for your little one is important, but so is making a journey as hassle-free as possible.

Types of car booster seat

The style of car seats falls into the Group 3 category, and, if you’re unfamiliar with the groups:

Group 0 – suitable from birth to 10kg (around 12 months) – these are usually lie-flat carrycot options that combine with a buggy or pushchair chassis to form a travel system
Group 0+ – suitable from birth to 13kg (around 18 months-2 years) – these can usually combine with a buggy to form a travel system and are also known as infant carriers
Group 0+/1 – suitable from birth to 18kg (around 4-5 years)
Group 0+/1/2/3 – suitable from birth to 36kg or 135cm tall (about 12 years)

High-backed booster seat

Often considered safer, the higher back and the wings and head protectors make them more suited to keeping your child safer. However, could you see your 10-year-old in one of these? Chances are, they’re already past the 135cm height limit by this point and probably won’t need a car seat, but if they still do… it looks a bit awkward for an older child. However, from ages four to around six, they could work very well for your child.

These booster seats may be held in place by your car’s three-point seat belt, but they may also be held in place by ISOFIX.

What is ISOFIX?

If you’re wondering what ISOFIX is, it stands for International Standard Organisation Fix and is possibly the best and safest way to ensure your car seat is secured. They’re effectively anchor points on your car’s internal shell, meaning when connected, the child seat is attached to the vehicle rather than held in place by a seatbelt.

It became common to see these anchor points in cars released after November 2012, but they were not an industry standard. Since November 2014, all new vehicles are legally required to have ISOFIX fitted.

How do I know if my car has ISOFIX?

Happily, ISOFIX on modern cars is easy to find and access; they’re generally under covers on the back seats with a logo that looks like a person sitting in a seat. It never used to be so evident in older cars, and you had to feel between the back of the seat and the base of the seat to see if the ISOFIX was there. This made fitting them very difficult. With exposed pinion points, this new system makes fitting car seats a doddle and takes seconds.
