Suspension self-bondage

[Like Ra]

EBay showed me this picture from Kinbaku Comic book, and I think that this semi-suspension "configuration" can be used in self-bondage. Or at least, a part of it.

   

My idea of semi-suspension is when there is a rope going from somewhere above to the ropes binding a person, so a part of the body is suspended, OR will be suspended should the person move from the current position, thus gently returning him/her back.

Another semi-suspension variant that should work for self-bondage:



I'd like to try it... What a EOTD...

I've always thought of something like this picture but have something like a pile of clothes or pillows to lay on top of, then as you wiggle the pillows scatter leaving you a couple of inches off the ground.
