These are wonderful, the fit perfectly. No popping off the corners. No sagging after sleeping on them. Cool on skin. No wrinkles. Love them !!!These 100% cotton high thread count sheets are very very comfortable. As advertised they "breath" unlike cotton/poly blend sheets. The high thread count = super smooth. These are, by far, the best sheets we have purchased to date. Presumably the cotton is long fiber egyptian cotton... probably spot on. First wash before use left ordinary amounts of lint in the dryer filter. However thick your mattress is (ours has a mattress cover) the fitted bottom sheet is deep enough to easily handle it. All good!This is exactly what I was looking for: a soft duvet cover with a zipper closure instead of buttons that keep breaking and allow the duvet to pop out of the cover.Very reasonably priced and washes well.Just love this brand. So soft and comfortable.I am very pleased with the quality and color of the pillow shams. Looks great on our bench. Should be easy to keep clean since it is machine washable.Very pretty color and covers our whole king size bed and almost to the floor.The seller worked with me.Liked.....used to add color to my new comforter
