Air sack alarm wakes you or else!

airsack alarm

If you're into extreme sleeping and don't want to lose your job for showing up late every day, you may just find the ¥98,000 ($800) air sack alarm to be a worthwhile purchase. The device uses a compressor, hose and inflatable cushion to make your bed so uncomfortable that you won't have any choice but to get up. Once the alarm is triggered, the cushion inflates and deflates at seven-second intervals. The alarm is sold by Japan's JR East train line, which claims this setup is actually used to keep conductors from oversleeping, which may help to explain why Japanese trains are always on time — and why you'll never get one of those dudes to crack a smile.
