I absolutely LOVE these sheets!!!  I bought some for my bed about a year ago and forgot I had them.  I put them on a week ago and they are truly the softest sheets ever!!!!  I loved them so much that I went back online and bought some for my son and my daughter!!  They love them too!!  Since we have only had them for a week, I can attest to their longevity, but they are SO well made and seems incredibly durable that I am guessing they will last a super long time!!!!!  I HIGHLY recommend these sheets :0)!!!!
