I ordered these for the deep-pocket aspect...I have a thick mattress with a 4-inch memory foam topper. The sheets fit well (not quite as well after a wash & dry, obviously, but they still fit.) The sheets are a little thin & I do feel like I slide around a bit...they may even be a bit noisy...but even despite all that, I actually do like the sheets. They are very pretty w/ the top embroidery (mine are purple). I will probably use these for quite a while--but I think for my next purchase, I would pick something a little thicker & less slippery.
