Here from another POV:

In case you are wondering what I am using as table-ish thing for my keyboard/mouse:

That’s an old sign my mate bongselecta gave me…
It can be switched from “wall mounted mode” to “table mode”.

My bed, an urban picture and a plan called lucy:

Please excuse the bad picture quality, I took these pictures with my mobile.

So here is the waterbed, sized 2x2m, that’s what Americans call Queen size I think:

Take a closer look:

Here is what you need: A simple tube/hose (length depends on your situation)

You stick one end of the tube into the opening of your waterbed, make sure it does not spill!

Put the other end of the tube outside, don’t bother with ups and downs:

Now here is where it might get tricky, you need to suck (yes I mean literally suck) on the tube to get the water flowing. Using this simple trick the water will flow through the pipe even though it goes up (pitches). The effect behind that is called (if I am not wrong) capillary effect which was discovered by Mr. German Einstein himself
You need to suck real hard, so that you create some kind of maelstrom, undertow, pull etc

After approximately two hours the waterbed was empty enough to be movable (around 800 liters sucked out)

You can then move it around freely and refill it using another pipe. Make sure you don’t spill any water, else you get all kinds of crap growing under your waterbed…

You have successfully moved 1600 pounds / 800 kg (liters) from point A to B :)
