It's hard for me to find a polite answer to that question because after fory- five years of professional cleaning in thousands of homes I've had to dodge around dust ruffles while trying to clean around and under beds. They get butted by the dust mop and sucked up in the vacuum, and they're are the delight of cats-so they catch, snag, shred, stain, and fray. There are a million and one grimies that can land on a dusr ruffle, even if your kids don't watch Saturday morning cartoons eating cereal in their bed. And then to clean it after Rover's marked it and your husbands dirty boots have been parked on it you have to heave-ho the mattress. wash and dry the thing. run around the bed several times to reposotion it properly again. reheave and replace the mattress., then hope that the wrinkles hang out of it. That's a lot of effort to hide a box of sweaters. Worst of all. dust ruffles harbor and encourage fuzz balls; they don't prevent them. Unless you like to lose things under your furniture for weeks or months at a time, I'd do without dust ruffles. It makes more sense to keep the area under the furniture open and accessible for easy cleaning that try to hide what we know is collecting there.
