This is what I do..for several yrs I've changed out my ruffle to match the bed cover. Take your ruffle and sew a header to the top--like for putting a curtain rod thru. Buy some safety pins 2-3 inches and slide the mattress to give access. Pin the 'header' randomly around the top of the box spring. So easy to remove & launder--no removing mattress. I love this method and no damage to box spring at all.
