Description

The I-boost i-Size is a perfect solution for children who have outgrown their previous car seat but have not yet reached a height of 150cm and above.

This car seat is ideal for children with a height between 135–150cm, as it ensures that the car's seatbelt will pass over the shoulder and chest, minimizing the risk of injury that could occur.

It is lightweight (weighing just 2.5 kg), so you can easily move it from car to car. It can be installed in cars with and without Isofix.

The I-boost i-Size car seat has been tested according to the latest R129 i-Size standard, meaning it has passed rigorous testing.

Suitable for all types of cars

The I-boost i-Size car seat can be installed using Isofix, but you can also use it in older cars without this feature. 

This makes it versatile and suitable for any car.

Ergonomic and Comfortable Driving

It features convenient armrests for pleasant driving and ensures an ergonomic posture. It is also wide and large, which means it is comfortable even for older children. 

Finally, it has an additional layer of soft memory foam in the seat.

Lightweight and comfortable to carry

It is lightweight, weighing only 2.5kg. This makes it easy to move from car to car, and the flexible installation means you can effortlessly place it in your car or in the grandparents' car.

  • This review is about the colour: Green

    It is very easy to install and remove, fits in the trunk space or in the footwell of the rear passengers in case you need the back seats.

    This review is about the colour: Black

    Nice, comfortable, excellent. It looks like other chairs from other companies that have double and triple the price. I didn't understand why until I bought it and installed it. So when the isofix is clicked in and if the seat belts are tucked into the seat, like in my Alfa Romeo, the seats fall over the belts and make buckling them from difficult to impossible. After many attempts, I had to unclip the isofix and use it as a regular chair. And I have the unanswered question: did the company's designers not bother to measure or look at a car manual and calculate the width so that it wouldn't cover the seat belts? Did they just make it randomly?

    Nice booster but it is a little wider than I would prefer and "covers" the entrance of the belt and the kids have difficulty tying it

  • This review is about the colour: Black

    Wide seat width, to the point that it makes it very difficult to fasten the seatbelt! An extension had to be added to the buckle of the seatbelt for it to close.

  • This review is about the colour: Pink

    My rating is purely about the comfort of the seat. As for quality, apart from the plastic isofix arms, it is of good quality. Unfortunately, the seat is not soft or comfortable at all. Our little one has said that she doesn't sit comfortably, and indeed the seat doesn't have a cushion for the child to sit comfortably. I do not recommend it, and fortunately, I did not buy a second one. I will look for something else.

    Very good seat and stable. You must definitely get a booster with isofix! We saw other kids with boosters using a seatbelt and they offer no safety in case of an accident, just elevation and convenience with the seatbelt. With isofix, you are sure.
