<p>The upper and lower layers are composed of a soft layer (5) and a semi-hardened layer (6). And on the total surface of the upper or lower layer there are many projections (2, 3) between which many vents (4) are penetrated. An airbag (7) is attached to the floor of the semi-hardened layer, and to the airbag (7) a fan motor where a timer and a speed controller are attached is connected through an air-sending hose, thereby for warm or cool or natural (in a natural temperature) air to be supplied. So in particular, it is expected that this invention will heighten the efficiency of the use of 'mattress' chairs, mattress beds, mattress sofas, and general mattress products by way of connecting it with a warm or cool ventilating system.</p> |
