That depends on what or which part of your ironing board cover needs to be replaced. Your ironing board cover consists of a top and bottom layer. It is highly likely that only part of your ironing board cover is worn out. When one of the two is worn out, all you have to do is replace that part. So that's only a top layer or just an underlay. Are both parts worn out? Then choose a complete set. Then a loose top layer will not suffice.
