Hmmm, I could have sworn these were described as "Deep Pocket" when I ordered them. Perhaps it is my mistake or perhaps it has been corrected. In any case: Deep Pocket is what I was looking for and these are not. The current description does not suggest that they will fit a 15 inch mattress but just in case you are wondering - They don't. The corners will stretch over the corners of the mattress but the bottom of the mattress shows along the sides. Other than that they are very nice sheets. I love the weight, feel, and color. The other reviewer that said these are thin must be finding some freakishly thick sheets elsewhere. These really seem quite plush to me.
