For about five years, I have woken up every morning in pain. Literally. My shoulder, back or hips would ache and it would take me an hour or so each morning to get loose. I chalked it up to getting older. After one night on the Wave Hybrid, I NO LONGER WAKE UP IN PAIN!!  I thought it was a fluke. But morning 2, morning 3, no pain!!  Month 2, still no pain. I actually look forward to going to bed again instead of dreading it. I can lie on my back again after a decade of not being able to. If you’re thinking about it ... do it! It is worth every penny.
