A vacuum bed is a device sometimes used in BDSM play. A
person is placed in a latex envelope spanned by a frame and a suction pump or
floor vacuum removes most of the air in the envelope. The frame can be either a
simple rectangle of pierced pvc pipes, joined by pvc joints, or three
dimensional frames of various sizes, with a similar pvc construction.
There are several ways that the vacuum bed can be designed
to facilitate breathing. The most common is a tube running from outside of the
vacuum bed into the person's mouth. A second option is a reinforced hole that
is positioned so that the mouth protrudes. A third option is a reinforced
gasket through which one forces the entire head. Incorporating a related
fetish, some vacuum beds use a gas mask to facilitate respiration.
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. There is also a danger of positional asphyxia, as well as the other
dangers associated with bondage activities.
