Worst set of sheets I've ever bought! The pillows slip out of the ends of the pillow cases--even with the case end tucked under. The standard fitted sheets do NOT fit a standard mattress. My mattress with topper is 13". The ad states the sheets should fit a 14" corner, but the corners barely fit over the mattress so I needed to buy straps to keep the sheet in place. There's at lease a 3 inch gap along the sides. When I pull one side to tuck under the mattress, the other side rides up.
