Foreword Our bed skirt is elastic and could be hooped on the mattress. If your mattress is too thick, you could pull the bed skirt to the bottom of the mattress. If your mattress is thin, you could pull it to the top. Please measure the height of the mattress to the floor before purchase it. And we provide a variety of colors, sizes and heights to choose from. Please free replacement on Amazon if size or height aren\'t suitable. Difference 1It fits easily and hangs nicely. There are the two bottom corners and the top elastic runs from one top of mattress corner to the other. There is no skirt fabric at the top of the bed by the side of the wall, it just slips around the entire mattress. Very easy to put on. One person can easily do it 2 We used brushed microfiber to product it, so we have confidence in quality. 3 We offer many colors(teal, taupe, white, coral, blue, black, purple and pink, yellow) and good quality meterial, which is thick enough. 4 It was stitched by tight elastic for one inch, which protect you to use a long time.
