ISOFIX or Rotating Car Seats – Which one is better?

ISOFIX or Rotating Car Seats – Which one is better?

Making your car safe for your young child means knowing quite a few technical topics, including ISOFIX.

Picking an ISOFIX car seat is definitely a good decision since it’s one of the safest ways of travel with a baby but if you’re a first time parent or have just never owned one before, there are some things you need to know about it beforehand. Another good option would be to pick a rotating car set. While both are safe, make sure you pick what works best for yourself.

What is it and what makes it such a safe pick for any parent out there?

ISOFIX is a standardized car seat fitting system that automatically locks your car seat or seat base onto two ISOFIX fixing points (metal clips) between the seats of your vehicle. This way, you won’t need to use the seat belt anymore.

As for the reason why you should choose it instead of other such systems available on the market, it’s because there is a much smaller chance of installing the car seat incorrectly than when using the seatbelt.

The baby versions need an additional car seat base while the toddler recommended ones can be installed with either ISOFIX or the seat belt.

Finally, for child car seats, to make them as safe and as stable as possible, you can use both the ISOFIX and the seat belt.

Here’s what ISOFIX brings you:

– As mentioned before, there is a really small risk of faulty installation thanks to the indicators,

– There is a permanent connection between the car seat and the car to protect your little one from the force in the case of a sudden brake.

– Thanks to the ISOFIX base, the installation and the removal are quick and convenient. The Click & Go installation feature lets you fit the baby seat onto the base with just a click, removing it just as easy when on the go.

ISOFIX and i-Size

The i-Size is obligatory for ISOFIX car seats since they reduce the risk of an incorrect installation.

However, you should keep in mind that i-Size does not replace the legislation.

So does your car already have ISOFIX?

Most likely! This is because ISOFIX has been made a standard in most new cars starting with the year of 2006.

Furthermore, at least 60 percent of European cars have it so yours most likely does as well.

However, it makes sense that you’d want to know for sure so there is a very easy way to learn by just checking the user manual of your vehicle!

If it does have it, you can also notice the ISOFIX logo on or a label at the very base of your seat.

The system features approved child restraint anchors on the lower rear part for some added safety.

Of course, even without all of that, your child would be safe with just the two anchors but in case an accident takes place, tilting forward and pitch rotation can happen which is why the third anchor point of the ISOFIX system is so important.

This third anchor is able to secure the upper part of the child’s seat backrest (Top Tether) or a Support Leg.

Both of these are anti-rotation systems that will bring any parent a lot of peace of mind.

As mentioned before, in the eventuality of a car accident, the anti-rotation system can do wonders!

Usually, there are two stages:

The speed and the deceleration cause all objects as well as the child’s body to be thrown forward at the same speed that the vehicle was traveling.

When the car suddenly stops, the child seat recoils, this being the second stage. But, if you have ISOFIX, the third anchor point stops the child seat from ever tilting forward or rotating.

Even though all the restraining force is found in the lower anchors, the anti-rotating system is what really keeps the chair in place and prevents your little one from being violently thrown forward.

It is important to understand that while a seatbelt provides some extra safety normally, it is not enough to act as an anti-rotation system.

In other words, using an “ISOFIX” system in combination with a seatbelt is not considered a CRS with ISOFIX anchoring.

In fact, the ISOFIX system particularly avoids employing the seatbelt so that any errors when installing the child seat can be avoided.

Before you purchase a car seat, you should also know some of the most common types of anti-rotation systems:

– Top Tether

This third anchor point is a strap able to secure the upper part of the backrest to the back of the car seat or sometimes, even to the trunk!

It is located on the trunk floor or on the rear side of the car’s bench seat and to find its location, you need to check the car manual or identify the position of the logo.

– Support Leg

The support leg is another type of third anchor point and an equally as efficient alternative to the Top Tether.

This type can be used with child car seats recommended to the 0+ age group so from the very beginning of your child’s life no matter if you have a rear facing or forward facing seat.

As the name also suggests, this is a leg that has to be extended until the point that it rests on the car’s floor.

– Lower Tether

This is yet another system that will make sure to prevent rotation in the case of a car accident.

It’s a strap coming out from the back of the car child seat and needs to be secured to the vehicle’s floor in order to increase safety.

Usually, it also attaches to the front seat guide rail.

Of course, there are some manufacturers that have come up with some other systems which will help in avoiding the recoil as well. For instance, the Pivot Link!

– Pivot Link

In this case, the connectors aren’t fitted to the bottom of the child seat but are, instead, set a certain height so that if a frontal collision happens, the connectors’ rotation can push the child seat down and absorb that energy.

Furthermore, it can be used at the same time as a Support Leg or a Top Tether for some increased safety.

All you need to keep in mind, however, is that it’s been created to only work for built-in forward-facing child seats.

Now that you know all you need to know to make sure your bundle of joy will remain safe while in the car regardless of the situation, here are a few great car seats you can use along with the ISOFIX system as well as a couple of great ISOFIX products in case your vehicle does not already feature it!
