I have a boy of a Jahr.So true size grade real super.Alle edges and corners he takes with his forehead with.The self-adhesive foam-like protective corners are easy genial.Sehen not super chic but not ugly. The corner protectors are padded quite thick. And our little one loves to push his little finger in there, to see how the dent is just again. Even the Beistest it has carried bestanden.Keine quirks or damage them. So all in all great products!
