I have had back surgery and have hardware in my back.  Every morning I would get up stiff, hurting, walking like a little old lady without her cane.  I would sleep best for 4-6 hours then I would HAVE to get out of bed. I just couldn't stand to lay there any more.  Now, since getting this mattress pad, I am having some of the best sleep in years.  I don't get up hurting every morning. I am no longer stiff. I am no longer heading straight for my pain pills to try to recoup from what little sleep I just got.  Now I am getting 8 hours and it has made a WORLD of difference for me.  Thank you Wayfair.....you changed my life!!!!!!!!!!!
