I *think* I may have found the one. I have tried sets up into the many thousands of dollars. I never tried the lower lines of the name brands. So, today I went to a true mattress store and tried all the ones I have tried before. The Simmons WOrld Class, NXG, Kingsdown Sleep to Live, etc. I move to the next one in the row and it feels "right." I lay a while and think it must be the one and that it must be very expensive. It is the CHEAPEST ONE I tried! It is totally different from any of the others. It's natural latex. Not memory foam, not inner spring. Latex. Who would have guessed. And it has the best warranty of any I looked at 20 years non prorated. It's a Natural Response by King Koil.
