After years of neck pain and countless unpleasant purchases on so called cure all pillows. My wife and I did some research and stumbled upon the Dosaze orthopaedic pillow. It looked and sounded very promising with real people testimonials. So we bit the bullet and purchased a set of Dosaze orthopaedic pillows. After about 3 weeks my wife absolutely loves hers, for the first time in many years she is waking up without neck pains. And is sleeping through the night with less tossing and turning due to discomfort, pain and pillow sweating. She claims that she is waking up feeling more rested and ready to tackle the day. As for myself I have experienced some similar positive results. Including the low contour of the back of the pillow allowing my CPAP nasal pillow mask being able to freely vent co2 from the top of the head vent. However I am also a side sleeper, and when sleeping on my side there simply is not enough thickness to support proper alignment of my neck and head. Causing me to reach for a different pillow during the night and not returning to the Dosaze when I return to sleeping on my back. Because of this I have returned to my old pillow, so in reality I haven’t been able experience the Dosaze full potential and benefits. However there is hope yet because, since our purchase of these pillows a thick version has become available, I wish it was available at the time of our purchase. Unfortunately I am not able to return my pillow because, somehow my daughter ended up with custody of my Dosaze orthopaedic pillow. And sadly like many other families we have been hit hard financially, so purchasing the thick version is currently not in the cards. So for now I am doing without and wishing that I could be dreaming on a Dosaze with alone with my family.
