I selected these flannel sheets after reading other reviews and comparing a number of other brands. As stated in the description, I had hoped they would suit a thick mattress. They do so barely. After only two washings, the cloth already appears worn and outdated. I followed the label's instructions. The linens seem dirty and are piled high. These are just an expensive version of a cheap flannel sheet. Since it's too late to turn around right now, I'll use them. In the past, I've used brands with unquestionably greater quality.
