Laying flat may be a bit of an issue, as most g-force machines use centrifugal force to induce the g-forces. Thus I'm not sure if you'll be able to get a good answer. While sitting, the principal cause of damage is lack of blood supply to the brain. Fighter Pilots typically wear a G-suit that consists of a set of pressure coils(filled with gas or liquid) that constrict the body(and blood vessels) in the legs, thus keeping blood supply to the brain. 6 g's is pretty grumpy, 10 is downright evil, 25 methinks would hurt a lot. Such a waterbed device would likely keep someone from going "squish" at 25 G's maybe a little. |

This page has some useful info: http://www.vnh.org/FSManual/02/02SustainedAcceleration.html This was a good article too: "By 1958, these studies had revealed that humans have the potential to withstand 46 G and a force of 10,000 pounds for a quarter of a second, forces that were well in excess of those anticipated for spaceflight.19" http://www.vnh.org/FSManual/02/02SustainedAcceleration.html |

A waterbed will only cushion sudden changes in g-force (by deforming to allow the body to essentially accelerate slower than the maximum instantaneous acceleration) - sort of like a shock absorber - it will take a little bump without a problem, but if you drive off a cliff it really doesn't matter what kind of shocks you have. |
