We have a California king bed on an adjustable base. I was trying to figure out which skirt fits the part that holds the mattress to the base when I saw these elastic ones. I was worried it might pop out when adjusting our bed, so I added some T-pins on the corners and two pieces on the sides of the bed where it "breaks" to adjust. I've included some photos to show the pins and where I used them. I'm an 18 inch height which is quite long when the bed is flat but it's great when we adjusted. In the photos I didn't wash the skirt as I wanted to make sure it worked.
