REVIEW: BESAFE – iZi Flex FIX i-Size – Stage 3

If you have young children, you will know how difficult it is to choose the right car seat.  And it’s not only this, because if you have more than one child it is even harder to find one where you can fit three comfortably in a row. When the time has come, I have often spent hours scrolling the internet, comparing brand after brand and still not being any further ahead several hours later from where I started. With so many on the market, which car seat do you choose? It’s easy, the BeSafe iZi Flex FIX i-Size

**We were gifted the BeSafe iZi Flex FIX i-Size in exchange for an honest review. All thoughts and opinions are my own.


With three young girls, we have had our fair share of car seats and whilst safety is so important to us, so is the need to fit 3 car seats across the back of the car. Putting one in the boot wasn’t an option for us (we do have a seat in there!) as we had the buggy to fit in and all the bags, boots and wellies that come with adventures with three under 5 so size had to be factored in.

The twins are now 5 and so it was time to get them stage three car seats. We had been asked by BeSafe if we would trial their new Stage 3 iZi Flex FIX i-Size to which we agreed. The main draw to us saying yes to this was because we were told you can fit 3 seats comfortable all in one row – perfect for large families of those with multiples!!


Who are BeSafe?

We hadn’t heard of the brand BeSafe before. Sometimes it can be daunting to buy a product when you haven’t heard of a brand as you don’t always know of the quality or safety levels of the product. However, BeSafe are one of the top Norwegian brands of cars seat for children but are only just making their way over to the UK.  BeSafe are a Car Seat brand who pride themselves on being the safest in the world! They have recently been awarded the highest accolade from a German Safety test.


iZi Flex FIX i-Size – Stage 3

The BeSafe iZi Flex FIX i-Size is the first booster seat (stage 3) on the market that fully complies with the new safety requirements.

What age is this car seat suitable for?

This car seat is a stage 3 car seat which means it is suitable for children 4 – 12 (but please read the guidelines on the website too).


How safe is the BeSafe iZi Flex FIX i-Size

The BeSafe iZi Flex FIX i-Size is approved to the latest UN R129 regulations. These are the highest demands to ensure your child’s safety is not compromised. They have additional side impact protection to absorb additional force. It has three layers of side impact protection and the headrest is shaped for the highest safety and comfort. The lockable shoulderbelt guiders at the headrest ensures that the belt is always at the right height for each individual child.


Does the the iZi Flex FIX i-Size feel sturdy and safe?

Absolutely. Safety is key for us. Once the car seat is in place in the car, it stays in position. Whilst the seat itself is very comfortable, it is also very sturdy and well built.


Let’s talk safety features. Does the the iZi Flex FIX i-Size comply with new i-Size regulations?

Yes, and more. The BeSafe iZi Flex FIX i-Size car seat meets all of the newest regulations and is the first booster seat on the market that fully complies with these. The BeSafe high back booster seat protects your child with safety features that even go beyond what is required by the regulation.


How does the iZi Flex FIX i-Size install in the car?

The instructions for the BeSafe iZi Flex FIX i-Size are on the side of the car seat which makes it really easy to follow them. The seat itself has retractable Isofix connectors so you don’t have to use them if your carseat does not have Isofix anchors. However, to fit the Isofix connector simply pull the handle on the front of the car seat and the connectors come out so that you can easily click them onto the anchors. You then just need to push the car seat back into place to secure it.

There is then a knob on each size of the seat which you turn to raise the back of the carseat & seatbelt guide to the suitable height for your child. Detachable bumpers (Side Impact Protectors) are included to go on the outside of the carseat for enhanced protection. You then use the car seatbelt to secure your child in the seat.


A padded cushion (foam glider) is also provided that wraps around the seatbelt on your child’s chest to make the seatbelt more comfortable and safer (prevents the chin hitting the chest in an accident). The seat then has a securing point for the seatbelt between the child’s legs so the child cannot slip out from underneath the belt.


Does the BeSafe iZi Flex FIX i-Size feel securely installed, once in place?

Yes, even when tugging and the children pulling themselves in and out of the car, the car seat retains its position.

How is it strapping your child into the seat?

With the Stage 3 BeSafe, you use the main seat belt to strap your child in as opposed to the 5 point harness they have been used to for the last 5 years. I will be honest and say it has taken the girls a bit of time to get used to it but after a few weeks they are more than happy to wear it.  The foam glider which sits on the seatbelt has definitely made it more comfortable for them to wear.


What do you think of the size and weight of the car seat?

The BeSafe iZi Flex FIX i-Size is actually fairly light considering the size. It has a handle at the top to make it easy to carry and I am able to carry them both together. Whilst the car seats are big, they have to be because they are for children up to age 12 but they are not bulky even with the isofix base. I am very impressed with them.

How do you adjust the height/size of the seat as your child grows?

Adjusting the car seat is easy. There is a knob on each side of the seat which you turn to raise the back of the car seat up and the seatbelt guide raises up at the same time. Therefore, it is a simple twist of this knob adjusts the seat to the suitable height for your child.


Are there different seat positions?

The seat does have two different positions. Upright and recline.  The recline position is great for when the children get sleepy. Just pull the handle at the front and the seat slides forward which allows the back to recline.


What do you think of the design?

I really like the look of the BeSafe iZi Flex FIX i-Size. It comes in 8 different colours and a stylish design. It isn’t too clunky considering it has an isofix base. There is plenty of padding to ensure comfort and it is fully adjustable. The only thing we would add is a cup holder!

The seats come with detachable bumpers for the sides so that three car seats can fit across the back seat in most family cars. We have a Ford S-Max and fitting three car seats across the back is no problem – this is a real selling point for us. We then attach the bumpers on the door side of the outer carseats to make sure they are all snugly kept in position.

Which type of child/family is this car seat best for?

This car seat is PERFECT for those families whether you have one child or three because each seat has excellent safety features and yet you can fit three of them in a row next to each other. This is a real selling point for us with multiples and a toddler.
