<p>A mattress cover comprising a base layer, a top layer and an internal volume defined between the two. The internal volume (302, figure 3b) contains a fluid permeable spacer material (502, figure 7), e.g. including polyester microfilaments. The base and top layers are connected around the perimeter of the internal volume. An air inlet 304 is provided in the mattress cover to allow air to enter the internal volume and move through the fluid permeable spacer material. A plurality of fluid outlets 312 are provided in the top layer to allow the air introduced via the fluid inlet to escape from the mattress cover. The mattress cover may be connected to a humidity controller which monitors mattress and inlet humidity which controls inlet humidity and temperature accordingly by use of (de)humidifier (112, figure 1a) and heater (116, figure 1a). Such control effectively deters dust mite infestation and is useful in aiding persons with allergies or asthma. Furthermore, herbal aromas may be introduced for therapeutic effect.</p> |
