What a comfortable set of sheets that give me a nice  feeling Everytime I get in bed . These sheets are 400 count thread and are cotton . I'm really impressed with all soft they feel and how well the fabric was stitched together .  This whole set came with the fitted sheet and flat as well as 2 pillow cases. I love how when I feel hot the sheets can help cool.me.down and I don't feel so hot plus the pillow cases help keep you cool as well plus they don't shrink when you wash them . Very impressed with the quality of these sheets and will be buying more in the future I highly recommend them
