Many people hear things about foam mattresses that are not always true. One common myth is that a foam mattress is always too hot. While some older models used to trap heat, most newer ones are made with cooling layers or breathable designs. Another myth is that foam mattresses are too soft and don't give enough support. In fact, many foam mattresses come in different firmness levels and can support your body well, especially if you sleep on your back or side. Some also think that a foam mattress has a strong smell that never goes away. Most foam mattresses do have a slight odour when new, but it usually fades after a few days. People also believe foam mattresses don't last long. However, a good quality foam mattress can last many years if used with care. Lastly, some think foam mattresses are only for younger people, but they can be a good choice for all ages. Before making a decision, it's helpful to learn the facts and not rely on what others say without checking.
