I have just found out that the car seat I purchased for my son 2 years ago has failed safety tests by consumer advice website Which?
The Asda Nania Trio Plus is suitable from groups 0/1/2. It was in tests for group 2, where the adult seatbelt is used across the childs body that the car seat scored 0. Luckly my son is still using the 5 point harness (group 1), though this didn't score very highly.
As a good will gesture Asda are willing to exchange the car seat for a newer model or offer a refund. Which I think is really good of them. Guess where I'm going on Friday.
I have included a link for the Which? report and Asda's advice if you have a car seat of this type. Apparently it also affect a Kiddicare Maxi SP car seat as well and people are advised to contact Kiddicare who will offer a exchange or refund.
