a second chamber;

a second valve through which the air pump inflates the second chamber;

a second switch to activate the air pump and open the second valve;

wherein the air pump has a first pair of electrodes and a second pair of electrodes, the air pump operating in a first direction when the first pair of electrodes contact each other, the air pump operating in a second, reverse direction opposite to the first direction when the second pair of electrodes contact each other, and the first switch controls the air pump to operate, and the second switch also controls the air pump to operate.
