These bed are made for earthquakes but I find these pretty scary. There are lot of different types of these beds and you'll see how they work in the video but what happen if you let your legs out of the bed or even worse, if you let your head out ? I don't know if somebody ever tested it but I'm sure this will not be me, I couldn't sleep at all. There is also food and other stuffs under the bed but how you can access it ? So much questions but if it can save lives it's cool to use it. An you, what do you think about ?
