Why is this the answer?

The answer is desk because this clever riddle uses fun word tricks to describe a very important piece of furniture that you probably use every day at school or home. It is a special piece of furniture made just for you to work on. First, the riddle says, "You will find me with four legs, but no hair." Think about a desk or a table. It has four strong, solid legs to stand up tall and keep steady. Since it is made of materials like wood or metal, it does not have any soft animal hair like a dog or a cat. This first clue helps you picture the basic shape of the object. Next, the riddle says, "People ride me for hours, but I don't go anywhere." This is the riddle's best trick! No one really rides a desk like a horse, but it means that people sit *at* the desk for many hours. When you are writing, drawing, or doing your schoolwork, you are sitting there for a long time. This is the "riding" part. But even though you sit at it for a long time, a desk is a stationary object. It is heavy and grounded. It stays in the exact same spot and does not move or travel to new places. Finally, the last part of the riddle is a smart hint about getting ready for action. "Jerked or turned on, I always manage to be ready for work." Your desk is always prepared for you to use. You do not need to turn it on with a switch or plug it in. As soon as you pull up your chair, you are ready to begin. The "jerked or turned on" part might be about opening a drawer to get a pencil, or turning on the lamp sitting on the desk. It is a helpful friend that supports all your books and papers while you get your most important work done. That is why the answer is desk.
