At 55, I wanted to treat myself and improve my sleep. I got a new bed, new sheets, new pillow and to finish it off I got a new Winssy pillowcase and then came back and bought another one. From day 1 my sleep has slowly improved and now I am getting at least an extra hour that I had not achieved as long as I remember. The pillowcase is silky smooth and very comfortable to sleep on. It seems very well made, but the test of time will sort that out.
