These are the worst sheets. The elastic on the fitted sheet is useless, it is a super thin piece that does not hold the sheet in place. The sheet itself is huge, definitely not the size of a king mattress—which cause it to wrinkle and bunch up as you sleep. Why can’t sheets be made to actually fit the mattresses? And although not microfiber the material is “sticky”. The top and bottom sheet will not slide or move with you as you turn over. I bought them, washed them, slept on them one night, then took them off the bed and threw them away. That was a hundred bucks wasted.
