"BEST PILLOW EVER and I truly have tried many types ranging from $100 down, synthetics to hard memory foam and none of those have given me the comfort this pillow, or should I say THAT KUSHN has. I used to wake up regularly with a stiff neck and a pain in my upper back and shoulder and not a single time since owning this pillow has this occurred. I am primarily a side sleeper but also sleep on my back. The quality of my sleep has also largely improved. I have been using this pillow for more than 2 months now and did not want to leave a review until I was completely sure."
