Worst mattress ever!

I paid good money expecting a quality product. I was assured that the warranty was great. I was wrong on both counts. Within a month a depression began at my hips. No problem, their warranty says when the depression hit 1.5 inches they will replace it. They sent a person out to measure and the company said, "No that's right at 1.5 inches, not over it! It’s now two years later and I sleep anywhere but my bedroom. I can't afford to replace it so there it lies. It got to where I could hardly straighten up after eight hours on this thing. Please don't buy one of these unless you are a masochist.
