Not like a water bed. No plastic cover/bag. Just a pool of high density fluid. Something like mercury, but non-toxic. Not wet. You just float on the surface. It would feel like when you stick your hand into a plastic bag and then into a bucket of water. Only more pressure. More bouyant. If it had a skin
tension and properties like mercury, you could use a pillow and blankets on it, and they wouldn't get wet. Super comfort.

This might be what you're looking for - it's liquid, dense, non-toxic and inert [kinemojo, Mar 15 2006]

Dare I suggest custard?
"You kids quit jumping on the bed, you'll break your ankles." |

You have a formula for this magic dense liquid that doesn't wet you? I think you should stick to wrapping it in plastic. |

"Dense liquid" usually gets a better response around here when called "custard". |
|

There are some metal alloys (typically some blend of tin, indium and gallium) which melt at temperatures below body temperature, but these are pretty expensive.
Also, what happens if you like to sleep on your stomach? Do you get a lungful of liquid metal?
Would this still work for you if it were a contained dense liquid, similar to a waterbed (i.e. WITH a membrane seperating you from the fluid)? |
|
| |
A sand bed with adjustable liquefaction generator? |
|
| |
Sorry I was late for work - my bed was set to "quicksand". |
|

I was reading about that Krytox material from Dupont. I'd love to see a sample of it. Does anyone know what it would look and feel like? |
|
| |
I don't know about a bed of chemicals... I think I'd rather sleep in a bed of jello!! :) |
|

Krytox is barely 2 times as dense as water, while Galinstan (6.4x dense) seemingly has no good surface tension, and would wet you. But should there ever be an applicable compound, i'd buy the bed. |

I don't see the purpose of not having a bag or the idea of a heavy fluid. I loved my old water bed and would still have it if not for my wife, but the advantage is the neutral buoyancy provided by the water. A bed of Mercury would be like sleeping on a bed of concrete. |
|
| |
A variable viscosity bed was put up on here that was much better of an idea. No offence, this is ok. Actually its really not thought out at all.... hmm. |
|
| |
Anyways, Ionic liquids would probably be the way to go, to avoid toxicity problems. |
|
| |
A bed of individual tiny polystyrene balls ' painted
with ions'# . Although, polystyrene fluff is a pain
to collect up. With a fluid, a vigorous dream might
end up with you painting your bedroom. |
|
| |
Something like a Fluorinert (a flourocarbon oil) might do
nicely. Dense, non-wetting and also non-toxic. |
|
| |
If you roll over you might suffocate. Although if it were an oxygenated fluorocarbon oil you might just carry breathing the fluorocarbon and all would be well. |
|
| |
Bung, do you suffocate on a regular bed from inadvertently
lying face down? I'm pretty sure your reflexes would keep
you safe even whilst asleep, if the liquid were dense enough
to keep you nicely afloat. |
|
| |
You are right - I am sure after one lungful of the stuff I would wake up choking and screaming. My reflexes are very keen that way. |
