Tying yourself or your girl friend to a bed is usually possible, but how exactly it should be done depends on the bed. Different beds need different methods. If the bed is strong enough, bondage can be made inescapable.
Tying a girl is usually easy, because girls are not strong and generally do not seriously try to escape. Use the ratchet cuffs to tie her legs and arms to the four corners of the bed. Make sure to use some soft material so that the metal parts of the cuffs don't touch her ankles. Girls are usually fragile. If you can reach the bed frame, use additional ratchet straps around her knees to spread her legs, and you can have your way with her. Any resistance will be futile.
The rest of this page is about strict self bondage. This is a bit harder, because you must able to tie yourself, followed by a time during which you cannot escape, and in the end you must be able to free yourself easily. In my experience, it is possible with most beds. If you do it properly, a very high level of safety can be obtained.
I will assume that you have no problems tying your legs to the corners of the bed. If you want, you can put some soft material between the metal parts and your ankles. In order to tie your hands to the bed, you must find a way to connect the ratchet straps to the bed with an ice cube in it. Both hands must have separate ice cubes. As long as your hands are separated you cannot free yourself. As soon as one hand gets free, you can reach the other cuff and free your other hand, so that the level of safety is very high.
How you exactly connect a cuff to the bed, depends on the bed. The ice cubes must be out of reach, and it must be impossible to shake them out. You must decide the exact position of the cuffs in advance. The position must be such that you can easily put your hands in them, while at the same time they must stretched as far as possible. Tie your legs, check how far your hands (your wrists) can reach, and put something small at the point that can can reach and aim at that. Typically you need to adjust the positions a few times. Test all of this before you start tying yourself.
The melting time can be quite long, and you should test it in advance a couple of times. Always make sure that both cuffs get released. If you don't, you are taking unacceptable risk. If the melting time is too long, you can wait a while before going in.
If you know the trick, getting yourself tied is quite easy. Connect another ratchet strap to one of the cuffs, and make sure that you can reach this strap with your other hand. Lock this hand first. After that, use the connecting strap to pull the other cuff closed.
