Lol! Vacbeds aren't dangerous at all. Well, the caveat to that is if you leave the face exposed... I don't reccomend encasing someont TOTALLY in rubber.
They can be a lot of fun, especially if you are the kind of person who is more touch-oriented.
It's best if the bottom is nude when getting into one, so if you want to add any insertables, do it before hand. Then you unzip the bed and slide your way into the bed and position your face in the hole. Some people like to be spread-eagle inside, but it depends on the size of the bed and your preferences. Then once you are in, the side is zipped up, the vacum pump turned on and then you wait a minute or two until the vacum seals you in. You may find it hard to move your limbs, but that's part of the appeal.
On the outside you can now get your toys out. It's helpful to have a sponge and a bowl of water nearby to put on the outside. Percussion toys don't have the same impact (pardon the pun), but sensation toys can be fun, especially vibrators. I heartily reccomend the Hitachi Wand to torture the victim with.
You can get one for about $400 or so, and make one even cheaper if you are willing to experiment with rubber sheeting and glue. I definitely reccomend playing with someone else's first if you are interested in getting one.
