We spend about one third of their lives asleep. We can survive longer without food than without sleep. Sleeping is very important, so the bed is important. Scientists say that the first bed was probably some leaves. Now, of course, beds are much better than that, and we have lots of choices. A common bed today lasts about 15 years, and most people change beds about five times in their life. Even with the thousands beds in the world, people still invent new ones. And some people are still searching for the perfect bed.
Knowing human history, people slept on layers of cloth, palm leaves, or furs. They laid these on the floor. In ancient Egypt, over three thousand years ago, the pharaohs were the first to raise their beds off the floor. They slept on light beds made of wood. You could fold the bed and carry it. :O Archaeologists..
