As some of you already know the mattress is not what you thought you were buying. Ours started sagging where both of us sleep after 2 years, but I waited another year before I made my first call. I was told from(Mattress Firm) that it shouldn't get any worse. We thought it was a memory foam mattress that was not suppose to sag or leave indentions. My husband and I are not large people. We barely weight 300lbs together. We were not told any of this info regarding "the bed is designed to conform to your body instead of your body conforming to the bed". "It's designed to cradle your body and relieve pressure". This is what the Claims Department told me. I can tell you that it does not relieve pressure. I get up EVERY morning hurting because of the pressure to my hips and back. They sent out an inspector from US Quality Inspection to check and measure our mattress. You can guess, he couldn't find anything wrong. It supposedly did not sag more than 11/2 inches. I know for a fact and I do have pictures that in different places it measured 2 inches. Needless to say, I am not a happy consumer of the Kingsdown Crown mattress. I will continue complaining to the company.
