These sheets are NOT wrinkle free. OMG what a hassle. The sheets wrinkle and the edges are the worst. I washed and dried them according to the instructions but no go. You feel all the wrinkly hard edges when you sleep and they make this weird crinkly sound as if you have plastic on instead of sheets.
I only gave this a 3 star because this was not soft enought for me. I must tell you that these sheets was nice and cool. I only wish that my skin was not so sensitive. I did have to send them back. If you are looking for cool sheets this is the one to buy. if your looking for soft this one is not it.
