In many countries of the world, today, it is a legal requirement for parents to ensure that their children are provided with a suitable child restraint system (CRS) when in a passenger vehicle. These laws apply to the UK, Europe, the USA and many other countries, and, unfortunately, many use different standards and regulations to cover these laws.
​The UK, Europe, and a total of 39 countries, including Japan, subscribe to the United Nations Regulation ECE R44.04. ​There are also other countries which will allow booster seats to be sold as long as they have this Type Approval, even though they are not among those signed up. This includes countries such as South Africa and New Zealand. More recently, for Groups 0 to I of CRS's R129 or i-Size has been introduced, which runs concurrently with UN EC R44.04 at the moment. This will be extended to include booster seats (Groups II and III) by 2018. However, this won't mean that booster seats approved under ECE R44.04 (and even R44.03) will immediately no longer be allowed, as there will be a number of years for this to be phased in.​ All CRS's need to be tested and approved under these regulations in order to be legally sold in these countries.

​Regulations are continually evolving and are being re-examined for additional child safety. For example, there is a current proposal that High Back Booster Seats must be used for children aged 3 - 6 (Group II) and Booster cushions (backless boosters) only permited for 6-12 year olds (Group III). This is expected to be in force by the end of 2016, although, will probably only apply to new booster seats being sold.

At R K Designs, we have taken this on board and have only requested approval for the Caboost® booster seat (cushion) for Group III. Furthermore, the majority of booster cushions rely on the use of a shoulder strap guide to enable there seats to comply for Group II children. We believe this is a risk, as many will neglect to use this, rendering the CRS unsafe.

​There is an added benefit inherent in the engineering of Caboost®. After a frontal impact, a child will be forced back onto the booster seat with considerable force. In addition to the comfort benefits of the Caboost® structure, there is the more important absorptive element. A child's coccyx (base of the spine) hitting a hard plastic booster seat, is potentially at risk of damage, but, with the absorptive properties of Caboost®, this risk is greatly reduced, if not removed completely. See our crash test videos in the video section of our website.

A booster seat is a simple CRS, designed to position the child correctly for the adult 3 point harness to sit safely over the child's shoulder (not on the neck) and for the lap portion of the harness to locate in the pelvic region and not over the stomach. Furthermore, there should be a 1 click disengagement in order to help the child leave the vehicle quickly in an emergency. This is why Caboost® does not use clips and other additional devices to guide the seat belt. One click and the child is free. This is as with almost any rigid booster seat, which uses arms to guide the seat belt correctly. Have a look at our Caboost® Manual to see more information on how to correctly use your Caboost®.
Caboost® has also been tested in the deflated state in order to ensure that, in the unlikely event that there is a puncture, the child's safety has not been compromised. Interestingly, in the USA, they refer to this as "Misuse Testing".
