I have a lexington queen firm coil mattress. It was purchased new about 2 years ago, and is in great shape, it has been professionally cleaned, so it is sanitary, it thick too about 11 inches. It has a slight pillow top. There is nothing wrong with it. It really is a great mattress for someone that wants to save some money. I would gladly keep it, i just moved to a larger place and I want a king.
