HM, thanks for sharing, but for those who have trouble with sleep it is useless. It is a nice gist or a toy for people who have too much money and don't know how to spend them. People who have insomnia or unstable sleep schedule would not use such sh*t. As a person who really care about his sleep, can say that to achieve the harmony is too hard. The only thing I can really advise is weighted blanket. sommio.co.uk helped me to realize my dream to buy it. It calms your body due to the weight and uniform heat distribution. Think that it is the best purchase for those who want to improve their sleep.
