I first received a set of these sheets in 2013 and loved them. They got softer and silker over time, but they were white and after 3 yrs or so of daily use (only had one set of sheets at the time), they were discoloring. So, I bought a new set in mid 2016. After only two months or so, the sheets started piling horribly. I thought I must have gotten a bad set, so I took them to the store and asked for an exchange. After some difficulty, the store agreed to exchange and I took home a new set of sheets. Now, only three months later, they are piling again. Nothing has changed in the way we wash or dry these sheets since the original set, so there must have been some change with the manufacturing. I'm throwing them away and trying with another store. Would not recommend.
