Sorry if this is already common knowledge but I was in mothercare yesterday and they were selling the BeSafe Izi Combi.
They had it on a prominent display and had leaflets about it too. I know Mothercares car seat fitting service does not have the best of reputations but I did over hear the sales person saying she'd choose it for her own children.
I think it's at least a positive step that more people will know about erf seats, I didn't know they existed til I came on here!
