 You know, about dust blades and your body giving off fluids. Oh, boy. Unless you have a mattress that was designed to live that long, like the smart bed by Instant Comfort that we carry. It has a 25-year industry-leading warranty, but it's a component bed. So you can make each side as soft or as firm as you like. It has big tooth zippers around the side. You can unzip it, open it up, and if a piece of it fails, you can replace it.
