Have read something about MDF being the new asbestos but there is a massive panel of MDF at the back of my child's cupboard (fitted wardrobe and the MDF splits between two rooms) - it was plain MDF (ie not veneered like in ikea) and we have painted it ourselves. Now slightly panicking that it is a major health hazard that will be banned one day and I've backed my child's wardrobe with it!!! Am I panicking ridiculously???
