​What is the purpose of a Child Car Booster Seat?
​A Car Booster Seat has one specific function and that is to elevate and position your child correctly in order that the motor vehicle's adult 3 point safety harness can be used without risking damage to the neck and abdominal area.

​In March 2017 the UN ECE R44.04 regulations were changed as there had been a growing concern that Booster cushions (backless booster seats) do not perform this task adequately for smaller children, who fall into Group 2 (15-25Kg). So, since these changes have been implemented, no booster cushions can be manufactured for Group 2 children, only for Group 3 (22-36Kg).

​So, is a Booster Cushion (Backless Booster Seat) Safe and Legal?
​Any Booster Seat that has been approved under the UN ECE R44.04 regulations has been thoroughly tested by an approved technical facility. These include dynamic crash tests, rollover tests and tests for fammability, toxicity and production quality control. UN ECE regulations provide for probably the most stringent safety requirements in the world. So, if it holds the UN ECE R44.04 approval, this is your guarantee that the booster seat that you buy, whether it is an ERF, High Backed, or Backless Booster, has been approved to provide the safety function that it is designed for, and, therefore can be legally used.

Look for the approval reference no. required under the UN ECE R44.04 Regulations.

What about Caboost?
As Caboost uses Air Cushion Technology, which includes an inflatable element, dynamic tests had to be undertaken in both the inflated and deflated state in order to gain approval under the UN ECE R44.04 regulations. So, there is no need to be concerned that Caboost would be unsafe in the unlikely event that it either partially, or completely, deflates when in use. However, we do recommend that some monitoring is undertaken prior to using Caboost, that it has been correctly inflated. If you go to our Crash Test Video Page, you can actually see a test of Caboost in the deflated state.

In addition, our observations of numerous crash test videos show that the child continues forward at the speed he or she was travelling when the car abruptly stops. The child is thrust forward into the safety belt and then pulled back sharply onto the booster seat by the safety belt. This safety belt recoil potentially risks the coccyx impacting hard against the booster seat. If this is a hard surface, then there is more risk of damage than if this was a cushioned surface. Hence, we believe that Caboost, with Air Cushion Technology, provides a safer recoil impact than hard booster seats. This safety belt recoil can be observed on our Crash test video page.
