I get up as if I were an invalid doubled over from pain in my spine. I can only sleep for approximately 5 hours. I can't take it anymore, it's not firm at all. My husband and I go to the middle when my husband lies down, the mattress sinks so much that I run towards him. and the guarantee does not cover any of this means that I lost all my money because now I have to vote for the mattress and buy another normal one of any brand
