I bought one for myself and tried it out 1st on my TempurPedic mattress that I added a 2.5" topper to... This stays put! While all of Sferra's are noted at 17" this one is the deepest yet- in fact deeper than Celeste! so you will enjoy! I don't need that crazy band around the side either to make it stay in place. The Sferra collection is all about careful precision that elevates any decor that it is put into. The Sferra Bottom Fitted Sheet is a great example of how minimal design can make an impact.
