An inflatable product includes a pack having a first vent with a first
valve, a second vent with a second valve, a third vent in communication
with the ambient, a first chamber in communication with the first vent, a
second chamber in communication with the second vent, and an air pump
pumping air into and out of the pack through the third vent when
activated in a first and second direction. A first switch structure is
movable between first and second orientations. The first orientation
opens the first valve and activates the air pump in the first direction
to inflate the first chamber. The second orientation closes the first
valve. A second switch structure is movable between third and fourth
orientations. The third orientation opens the second valve and activates
the air pump in the second direction to deflate the second chamber. The
fourth orientation closes the second valve.
