Polyvinyl chloride plumbing and electrical cover pipes are used in the assembly of low priced devices that will support mosquito bed nets. One such device is a frame assembled from components in a lightweight compact set with dimensions of 75 x 20 x 5 cm, weighing approximately 0.5 kg. It can be mounted on a wall or attached to a stand of adjustable height which is also made from plumbing pipes. This support frame provides minimum obstruction of view and movement as it is attached at only one point. It can be used indoors or outdoors either for sleeping on beds or on the ground. A second device is composed of short pipe sheaths attached to bed legs for easy insertion or removal of support poles.
