Just purchased another set of these sheets after using my first pair for six months. These sheets are a great quality and will last for many years. The more they are washed the silkier they become. I have a king bed so I learned to dry one sheet and one pillowcase together for 30 minutes and then do the other two the same way. No wrinkles or tangled sheets doing it like this. Always measure the depth of your mattress and make sure they will fit before ordering. I feel I have made a good investment with my sheet pruchase and hope to replace all my others with this brand.
