Happy Dreamer was designed based on the outcomes of bio-mechanical studies of the neck in sleep disorders research centres at Canadian and American universities. It was perfected using clinical findings on hundreds of back patients.
The Happy Dreamer comes in two versions: the Happy Dreamer high and low. If someone is broad shouldered or well built, we recommend that they opt for the high version. The high pillow will ensure there is adequate space between neck and mattress. The low version is usually sufficient for someone who is not well built, or in combination with sleep systems fitted with a really soft lowered shoulder zone.
