Why is it more comfortable for people to sit on the sofa than to sit on a chair, and why is it more

Sitting on the sofa, the contact area between the body and the sofa is large, and the pressure (i.e., pressure) per unit area should be comfortable for small people.

Because the contact area between the sofa and the human body is relatively large, the pressure is much smaller, so the human body will feel much more comfortable.

The sofa is softer than the stool, and sitting on the sofa, the force area of the body is relatively large, and the pressure is small, so it is more comfortable. >>>More

Answer: C

What is considered is the pressure, the pressure is constant, the force area is large, P=F s, s is large, and the pressure is small. >>>More

Sitting on the sofa and the wooden bench, the pressure on the two is equal, equal to the magnitude of the gravitational force experienced by the person But the sofa is soft, and the contact area between the person sitting on it is larger than the contact area on the wooden bench From the formula p=F S, it can be seen that the pressure generated by the person on the sofa is small Therefore, the upward force generated by the sofa on the person per unit area is also small Therefore, the person sitting on the sofa is more comfortable than sitting on the wooden bench
