In June 2013 Which? published results of their tests undertaken on the Nania Trio Plus car seat, The models affected are mainly those produced before December 2012. Although the Nania passed the EU regulations it failed on the more stringent Which? tests gaining an overall score of 0% for safety. These car seats are on the Do Not Buy list although the product has now been discontinued. You can read the report here:

Asda are the only high street retailer to have sold this particular model and are well aware of the Which? findings. I recently emailed them about this car seat as I had been using one since December 2011. This was their response:

"I'm sorry that a report has been published on Which? that suggests the car seat is unsafe to use. I can certainly appreciate your concerns especially as your child's health and safety is extremely important.

All car seats sold at Asda are tested to the same EU standards that are in force across the retail industry and do meet all legal legislation. Although the car seat met all the required EU safety standards, Which? carried out their own safety tests and it is on this test that it scored low.

As the car seat has met all legal requirements and isn't faulty, any replacement will need to be done through the manufacturers. We will support any changes to the legislations and are happy to work with the industry to advise on how we can make this happen.

Team Tex the manufacturer of the Nania car seats are happy to replace any of the old versions of the seat with a brand new, modified version as a gesture of goodwill".

The car seat didn't just score low, it scored, overall 0%. The Which? report states how they test the seats against what the EU regulations demand. Which? tests reflect collisions more accurately and they include side impact collisions whereas the EU tests do not.

Asda should make steps to ensure this becomes public knowledge and a full recall of the car seat should be undertaken immediately. As a parent who owned this particular model I am extremely concerned that there are many, many parents out there who do not realise the potential danger their children could be in.

The affected model has a serial number on the back on the shell. It will start with D12, then a year, then 6 digits. If the 6 digits are less than 131000 then that model is the one that Which? tested. As each car seat has a unique 6 digit code that means there could be a potential 130,999 car seats deemed unsafe in use today.
