Ridge in middle of bed, worthless warranty

The first 2 or so years it was pretty good support. The 3rd year it became less comfortable. We contacted the company and they said it was naturally going to have the impressions of the way you sleep in it. There was nothing they could do. We also told them since it is specific to our bodies we cannot rotate the mattress & therefore we are always putting our weight in the same spot. This is a very poor design flaw. We should have bought another Sealy Posturepedic, The salesman at Sleepy's was a good salesman he talked us into purchasing the $2,000+ supposedly "better" mattress. Well, it was a HUGE mistake! a 15yr warranty that means NOTHING! I will NEVER go to Sleepy's again! Sadly we told our cousin about Sleep to Live in the first year we owned it and he purchased one also. He is having the same problems we have had. When the bed is made it looks like its a hundred years old with the ridge in the center and the body depressions on each side! So here it is 7yrs into our 15yrs worthless warranty and we are off to purchase another mattress! Lesson learned!
