I am very disappointed with the sheets and will be returning them. I loved the color, but the sheets are a very thin, slippery material and the fitted sheet does not stay attached to the mattress...either the elastic is not tight enough to hold it in place  or the sheets are too slippery and the sheets come off at the corners and sides. In addition to that, the pillowcases were poorly sewn and had breaks in the pattern and incorrect overlapping of the stitching. The material was rated as cool for sleeping but the synthetic material actually retains heat and makes the sheets warm and uncomfortable.
