I suffer from chronic pain and decided to try this pillow. It took me several days to make a good fit; pulling foam out, moving it around and placing foam back in. I was finally able to get a great fit. I'm a side sleeper and this pillow now forms around my neck and cuddles my head. It has reduced the pain in my neck and head 60-70%. I am so happy. With the Tempur-pedic bed topper and the Tempur cloud adjustable pillow I now lie down in bed in great comfort. No more restless nights.
