I’ve been using one of these pillow for almost 15 years now. Before I started using it I had consistent neck pain. Have had zero pain since. I use a queen size; I think that is all they make now. If I’m on the road, I take it with me. For me it stays cool and I also do not have to turn it over(almost forgot that I had to do that with a conventional pillow).
