Unfortunately, mattresses don't last as long as we would hope. If you want your mattress to last as long as possible, you need to take proper care of it. Here are some things that you should be doing to take care of your mattress.
Mattresses are one of the most wasteful items we manufacture as a society. They are usually comprised of memory foam, which is a petroleum and chemical based material. They are usually wrapped in a plastic fabric like microfiber or polyester, with some fancy name so it doesn't sound like plastic. These mattresses, marketed under fancy and recognizable names, are made to last 5-7 years and when they wear out, are not good for anything. They end up going into landfills where they sit and do not decompose.
