Why is it more comfortable to sit on a sofa than a bench?

The sofa is soft, and the degree of deformation occurs when people sit down, so that the contact area between the sofa and the human body becomes larger, and the pressure becomes smaller. The bench is harder, not easy to deform, has a small contact area with the human body, and has strong pressure.

Because sitting on the sofa, the sofa is deformed, thereby increasing the force area of the human body In the case of the same pressure, increasing the force area of the human body can reduce the pressure on the human body, so it feels more comfortable

When the pressure is the same, people sitting on the sofa are more comfortable than sitting on the hard bench, which increases the force area on the buttocks and reduces the pressure on the buttocks, so it is more comfortable for people to sit on the sofa than on the hard bench. >>>More

Sitting on a sofa is more comfortable than sitting on a bench, mainly because the sofa is softer, which increases the (contact area) between the person and the sofa, and (decreases) the pressure while the (total pressure) remains the same.

(1) Sponges are relatively prone to deformation, and we can compare the effect of pressure by observing the degree of deformation of sponges >>>More
