Earthquake-proof beds designed to sense imminent disaster

An animated video that emerged online and was first spotted by Gizmodo shows various earthquake-proof bed designs that are scarier than an earthquake itself, Business Insider reports.

The designs appear to be related to a 2010 Chinese patent awarded to inventor Wang Wenxi,.

The beds sense when an earthquake is happening and lower the sleeper into a metal box that contains enough supplies to ride out the aftermath. A 2012 video from a Chinese trade expo shows a prototype in action.
