They are just ok.  I specifically ordered extra deep pockets.  I need at least 17 inches.  These are not, and the material isn't what I expected.  Oh well, my first Wayfair disappointment.  Cannot return them, because I always wash new sheets before I use them.  The elastic is a cheap thin elastic all around the fitted sheet.  If that lets go the sheet will be useless.
