NUREMBERG (Germany) Oct 30: A German schoolgirl has invented a “merciless bed” to ensure sleepyheads get up in the morning.

The bed raises the mattress one centimetre a minute after an alarm rings. After five minutes, the sleepyhead is rolled onto the floor.

“I constructed it myself”, Iris Klose, 16, said at an exhibition of inventions this week.
