Query: soft but flimsy

I had cotton fleece sheets before that I absolutely love, but I thought I would give the polyester ones a try. They are fuzzy on one side ony, but they are still soft. The bottom sheet pops off the edge of the mattress during the night if you toss and turn. For the price, less than half that than the cotton ones, they are ok, I figure I got what I paid for.
