The reason I noticed this tweet, is because right away I said to myself - this is exactly why the arc4life traction pillow was created. The arc4life traction pillow is very good for maintaining neck posture while sleeping on your side or back.The special contours on this pillow allow for a person to maintain the proper c curvature in the cervical spine.
I have had really bad neck problems since I was about 25. I have tried several pillows and none of them helped. I have been to the chiropractor and spent thousands of dollars on treatments. Again it was temporary relief but not permanent.
