Love them! Instead of grabbing clean sheets from the linen closet, I prefer washing these sheets and waiting. Rather than grabbing a clean set of sheets from the linen closet! Do doft, and fit pretty well over my thick mattress box spring. . I have a 4 inch topper as well so finding sheets that are quality yet affordable, fit and stay in place isn't always easy. But I seem to have the best luck with wayfair. Wayfair had become my default place for pretty much everything I need..or when I can't find locally. Or when I'm just plain lazy..9 times out of 10,  I know I'll find what I'm looking for right here.
