We are selling this because it didn't suit my husband and me (another set is also listed elsewhere). Includes a cooling reversible cover. Used for a few days, and the covers have been washed. It was packaged by being rolled up and compressed, so I will compress it as much as possible for shipping. I don't think there's any sign of use, but please refrain from purchasing if you are concerned. ➖Nitori Official Website➖ Reduces the burden on the body during sleep.
