<p>The number of dust mites increases dramatically under the favorable conditions of a bed tidily covered with all items used during the night like the pillow, the duvet and an additional counterpane. The invention proposes several kinds of support and holding elements attached to the head- or foot-board (6) or suspended from additional objects in order to allow air to move along the surfaces of the bedclothes during the day. Telescopic bars (2, 2a), lifting devices, rope and pulley systems and specific units disinfecting the area with ozone and other suitable substances are also included.</p> |
