It took me nearly four months. I work in accounting. Cervical spondylosis is very serious, and I often can't sleep. I feel very good after using this pillow. This pillow can be made into various shapes and can be used for traction massage. Now the quality of sleep has come up, and you can sleep until dawn. This pillow is really good.
Only on behalf of personal views, don't spray if you don't like it, thank you.
