The vacuum bed is both a bondage and sensation device. The user is unable to move significantly (although some wiggling is possible), and is unable to speak or see, depending on the breathing hole used. In addition, though, the sensation of the vacuum bed itself, as well as any other play (stroking, percussion, vibrations) are quite pleasurable, and some are much more intense than what would be experienced without the vacuum bed.
The vacuum bed must be used with the aid of another person, as the user cannot control the vacuum itself, nor escape the vacuum bed unaided.
