I can say that it has helped..the last few nights I actually slept more the 5 hours in a row...I will continue to give it a try. I know setting it up in a position to read has been great as well. The cost was a little more than I wanted to pay, but so far so good. I do have a tempurpetic mattress, I just wish I had the adjustable one. They did not have that when I bought mine a few years ago.. I am not ready to dish out the cash to buy a new bed.
