ABSTRACT:
A device is provided for removing air from a waterbed having a water/air valve. The device includes an elongated member having a length that is almost as wide as the width of the waterbed. A pair of smaller members which are parallel to each other and have axes that are perpendicular to the axis of the elongated member, are coupled to the roller support member. The smaller members are coupled in sliding relationship to the elongated member.
To remove air from the waterbed, the elongated member is positioned at the end of the bed farthest from the water/air valve. The elongated member is moved toward the water/air valve to compress the waterbed longitudinally. When the elongated member is adjacent the water/air valve, then the waterbed is compressed laterally in the area that has not been compressed by the elongated roller, by moving the smaller members inwardly toward the air/water valve.
