Have had these sheets for almost a year. They're great. The elastic all around the fitted sheet makes a difference. I've washed every week and the sheets are holding up well. The sheets recommend a warm wash. For the last few months, I've been washing in hot water for allergies. These sheets have help up better than others I have. Also, these sheets don't really wrinkle, which is nice. I only wish they would make this product in other sizes besides King and Queen.
