The surface area
It is possible to increase the amount of pressure by decreasing the area where force is applied. This is known as pressure magnification, where the same amount of force is spread over a smaller area, resulting in higher pressure.

Since Pressure is Force per Unit Area (P = F/A), there are intuitively two ways to increase pressure. You can either keep the area constant and increase the force being applied, or keep the force constant and decrease the area on which the force acts.
When a force is applied to a fluid in a closed container, the pressure increases uniformly throughout the fluid. This is because the molecules of the fluid transmit the force in all directions equally, resulting in a uniform increase in pressure.
The amount of force applied to an area is known as pressure. Pressure is calculated by dividing the force applied by the area over which the force is distributed. The SI unit for pressure is the pascal (Pa), which is equal to one newton per square meter.

pressure
Pressure can be increased by adding more force or reducing the area over which the force is applied. It can be decreased by reducing the force or increasing the area over which the force is distributed. Additionally, changing the volume of a container can also affect pressure, as pressure is inversely proportional to volume for a fixed amount of gas.
Lying on an air mattress would not significantly increase the pressure of the gas inside it. While your weight exerts pressure on the mattress, the air inside can compress slightly, but this change is minimal and typically does not lead to a substantial increase in pressure. The overall pressure change would depend on the volume of air and the amount of weight applied, but in general, the effect is minor.
If you increase the atmospheric pressure, the pressure will also increase. This is because atmospheric pressure is the pressure exerted by the weight of air above a certain point, so increasing the amount of air causes an increase in pressure.
Pressure is given by the equation P = F/A, where F is force and A is the area it's applied over. For a solid or liquid, you can increase pressure just by pushing harder on it. For a gas, pressure is approximately given by P = (n*R*T)/V, where n is how much gas you have in moles, T is the temperature in kelvin, V is the volume of the container, and R is a constant. So to increase pressure, either increase the amount of gas, increase the temperature, or decrease the volume of the container.
