I have had 5 back surgeries with 4 being major surgeries. I suffer from other structural health issues, so needless to say pain is a constant in my life. When this mattress first arrived I was hesitant that it would help me sleep without so much pain. Now I recommend to friends and family if they have a bad back this is the mattress to buy. I no longer wake up in excruciating pain. It is so nice.
