I have had medical issues and injuries to both of my shoulders and have had serious problems both with sleeping and with waking up in the morning with my shoulders aching from sleeping on my side. I was really reluctant to use this pillow since I am a side sleeper and have been since I can remember and did not think the pillow would work for me. How wrong I was!!! I pulled a new Adjustable Spine Alignment Pillow out of its plastic wrapper, did some minimal “fluffing” and layed down. Instantly I could feel the support to my neck and the stability of my upper spine. Before I knew it I was waking up the next morning without my normal shoulder pain and I felt more rested and ready for the day than I normally do. I highly recommend this pillow to anyone who suffers from neck and shoulder pain, upper back pain and anyone looking for a good nights sleep.
