Has anybody on here used a magnetic mattress topper? I read they are good for people who suffer from chronic pain. I have just purchased one out of desperation for a good night sleep. I am in such constant pain all over and can not get into a comfortable position. on a good night I sleep roughly 2 hours undisturbed sleep but oh boy!!! when I try to move position I almost need industrial crane to move and then its fighting with my legs as they wont stay still and the rest of the night is just broken sleep well no sleep really.
