Why Is A Firm Mattress Important?
To some extent, the best firmness or softness level for your mattress will depend on personal preference. Some may feel more comfortable on a firm bed, while others will feel better on a relatively soft bed.
However, there are also other reasons why a firmer (or softer) mattress can be desirable under certain conditions. Your sleeping position is one factor that can affect what level of firmness is appropriate.
If you sleep on your side, a softer mattress that can more easily contour your body’s curves may be the better choice. On the other hand, people that sleep on their backs or stomachs may find that a firmer mattress keeps their spine more neutral and aligned, instead of potentially allowing it to arch or round excessively.
Additionally, your weight can affect your preferred firmness level. If you’re big and tall, you might sink down into mattresses more, and they might feel softer to you. In comparison, the same mattress might feel firmer to a smaller person.
There is also some scientific evidence to support a connection between a firmer mattress and positive health outcomes, like less joint and back pain, better sleep quality, and a lower overall stress level. For example, a 2009 study found that for people of average weight, sleeping on a medium firm mattress helped reduce low back pain and made people feel more well rested and less stressed, relative to their old beds.
