Since purchasing my awesome steam generator I have just thought I needed to replace the foam under my ironing board cover-- but after coming across this item I realise that steam generators must make so much steam they just drip water through the ironing board. I love the concept of this and it feels like nice quality, and it is big enough for my size B Brabantia ironing board -- but I cannot understand how this is supposed to stay on the board??? And there are no instructions. There is a drawstring which I pulled after placing this atop the board which did somewhat tighten it around the board- -but no where snugly enough. It is not on smoothly or flat, and I don't see how I can get it to be. So I'm not sure if I can return this now-- but would definitely want an elasticised version!
