The person that said different strokes for different folks is 100% correct . I have a really bad back & have had back surgery . The surgery got rid of my leg pain that was caused by a pinched nerve in my back but didn't help my back pain . I bought a temper-pedic mattress & absolutely hated it . It had a trial period so I sent it back . The salesman jokingly called it the boomerang bed . Must have had a lot of them returned . I then bought a simmons backsaver . It is a pillowtop & I've had it for about four years & really like it . No signs of sagging or other breakdown problems . Next bed might be a sleep-number if I can get a trial period .
My sister has one in her guest bedroom & I have slept on it a couple times . From that limited experience I think it might be a very comfortable bed .
