Q. What are the disadvantages of a foam bed mattress?

Here are the disadvantages:The weight of a foam mattress can vary widely. The fact that a user doesn't have to flip them should make this less of an issue.It's been noted that because they envelop the body so completely foam mattresses tend to be warmer than traditional beds.It's possible that the mattress will feel softer than usual in warmer climates and firmer than usual in colder ones. The mattresses have reportedly been accused of having an unpleasant odor by certain guests. When they haven't been given enough fresh air this issue arises.
