Most beds will only require a 14-inch skirt to cover the box frame, but we also have 18 and extra long-21 inch skirts for those with higher platforms. When you choose a skirt, you will want to measure from the top of the box frame to the floor, then subtract a couple inches for a small gap. This will ensure the bedskirt doesn't touch the floor. Most are available in either a ruffled (pleated) style, or a tailored (flat) style. If you need an extra long bedskirt, we've got you covered.
