I took delivery of my new Levitex pillow about a month ago. Previously a night's sleep would be broken up into a number of short periods, as I would change my position many times during, the night and at the same time flipping my old pillow over each time. There was an initial settling-in period of about a week, during which time I got used to the difference in firmness and texture. However, now I sleep for much longer periods at a time and I don't think I've flipped the pillow once since it arrived! All-in-all, a great aid to a better night's sleep and I would highly recommend this to anyone having difficulty in sleeping comfortably.
