a rug is the answer
The answer to this riddle is "a staircase". Of course the staircase does not actually move up and down, but when you refer to a staircase directionally, you are either going "up the stairs" or "down the stairs". Its function in and of itself is to "go" up and down.
Temperature
It is easier to go down stairs because you are moving in the same direction as gravity, which assists in your movement. When going up stairs, you are going against gravity, which requires more effort. Additionally, the design of stairs typically favors descending with larger, more stable steps, while ascending usually involves smaller steps that require more energy.

An escalator is a moving staircase that transport people vertically between floors without requiring them to walk, while a lift (elevator) is a compartment or platform that moves vertically within a shaft to transport people and goods between different floors of a building. Essentially, an escalator moves people continuously, while a lift moves intermittently between floors.
