This is one uncomfortable looking alarm clock, instead of being woken from your slumber with sound or light this nasty Japanese gadget alarm contorts your spine.
To set the alarm you need to place an inflatable air bag under your mattress, which is attached via a hose to an air compressor, this in turn is connected to an LCD display. You then set the time you want to be awoken, lay nervously on the mattress and try to get to sleep.
When the alarm goes off the compressor kicks into action, inflates the bag resulting in the mattress rising up and down. So it’s a bit of a double action alarm, first you have a noisy compressor followed by a very uncomfortable moving bump, I think I’ll stick to my clock radio.
