What is the difference between firm and soft?
The obvious difference between a firm mattress over a soft mattress is that a firm mattress is stiffer to the touch and has less elasticity and a softer mattress compresses more easily when pressure is applied.
The firmness or softness of a mattress depends on the spring tension or overall construction tension within the mattress. Mattresses can be made with different types and quality of materials, resulting in different types of softness and support.
Advantages of a firm mattress
Sleeping on a firm mattress causes the body's weight to be evenly distributed, meaning that no one part of the body bears the brunt of the pressure, it also prevents the lower back from collapsing, which could allow for greater oxygen intake while sleeping
A firm mattress will generally be more comfortable, by sleeping on a firmer surface the muscles of the body are less strained and circulation is improved, this is because the bones absorb most of the pressure.
Advantages of a soft mattress
Softer mattresses are generally better for side sleepers, as they cushion the shoulders and hips better. On the side, a softer mattress also aligns the spine better.
A softer mattress is generally recommended for those who experience back pain and for lighter people, as a harder mattress may end up not compressing them at all.
Choosing what's right for you
The reasons that go into determining which is the best choice between these two sizes are going to be weight, health conditions and the position in which you sleep.
People who are heavier are likely to choose a firmer mattress as due to their own body weight they may find them softer and lighter people may choose a softer mattress as the mattress can support the weight very well and adapt to the curves of your body.
Then it will also depend on the position in which you sleep for example if you sleep on your back or stomach a firm mattress is better and side sleepers will prefer a softer mattress. Another factor is the pain or back problems or posture that you may have, generally people with these types of health problems choose softer mattresses to relieve pressure on the lower back.
Keep in mind that this choice is not only between firm or soft because between these two extremes there are several levels of comfort and softness that you can choose, plus your tastes will greatly influence your choice because maybe you have back pain but you sleep on your stomach and you like firm mattresses.
The objective of the mattress is to keep your body in a neutral position, this will keep the different parts of your body aligned in order to reduce the pressure on the pressure points of the body, in this way we improve the posture and we will get a great rest.
