to support
The answer is a bed. A bed has four legs, it sits on the floor with its legs, and "waits" for someone's legs to come and lie down on it.
4 legs
A lion has four legs.
Four. A cat has two front legs and two back legs.
they have paws. their front paws have 4 claws.
Long legs 1.25m above the surface of a Stevenson screen are meant to elevate the screen to ensure proper air circulation around the temperature and humidity sensors inside. This helps to prevent any interference from the heat radiating off the ground, providing more accurate measurements of temperature and humidity.

to prevent heat radiation and damage by people or animals
A Stevenson Screen has longer legs to elevate the enclosure above ground level, minimizing the influence of heat from the ground and surrounding surfaces. This design helps ensure that the temperature readings inside the screen are more representative of the ambient air temperature rather than being affected by heat radiating from the ground. Additionally, the height aids in protecting the instruments from direct sunlight and precipitation, contributing to more accurate and reliable measurements.
In observataries,the thermometers are kept in a wooden box with good ventilation and air movement.This box is called stevenson's screen

To allow the air to circulate
[object Object]
The sides of a Stevenson screen are louvered to allow air to circulate freely around the temperature and humidity sensors inside. This design helps prevent the sun's direct rays from hitting the sensors and affecting the accuracy of the readings. The louvered sides also help to reduce the impact of thermal radiation on the inside of the screen.
the stvenson screen has a air vent on the top of it so that air can get out
