It is not the rug; it is the alarm clock to wake you up early in the morning. It is designed so sharply that you have to stand on it to make the alarm off. You have no choice left but to get up.
The pressure sensors inside the rug make the alarm off when you stand on it. 3 seconds is the time it will take to stop the alarm. You can set the time that how long you have to stand on it to make it off. You will receive morning greeting from it as set by yourself.
