Here's an interesting historical tidbit. The phrase
make your bed comes from the days when people literally made their beds every night. (Typically, such beds were straw mattresses that were rolled up and stored next to a wall when not occupied.) The expression
get up, meaning
get out of bed was probably even more relevant then.
