In such instances a person will often throw off the covering while asleep, which will then result in chilling.
In warm weather when the
room temperature is above 70 F., a lighter covering is usually employed but the
moisture which results from
perspiration is still retained about the body by the insulating covering, causing personal discomfort and results in poor rest.
The obese and the bedridden are particularly troubled by these conditions of the air environment about the body.
Room air conditioners which have heretofore been provided for regulating the room
air temperature and
humidity conditions have the disadvantages of handling large volumes of air, requiring special electrical power, and are relatively expensive for installation, operation and maintenance costs.
Even with room air conditioners, the person usually employs some form of covering which insulates the body from the surrounding air so there remains no suitable means of exchanging the air between the body and the covering of the occupant's bed.
Of these causes the physical comfort of the person attempting to sleep or rest is paramount, for if a person's ambient surroundings are not conducive to their personal comfort, sleep can become extremely difficult to achieve, if at all.
If the temperature of the surroundings of a person is either too hot or too cold, restful sleep may be impossible.
Of particular concern is the case where the surroundings are too hot, because in such cases the body's ability to control its
internal temperature may be effected to the point where the body begins to sweat, and it is nearly impossible to achieve restful sleep while sweating.
While air conditioners are highly effective at coarsely controlling the temperature in a room, the customary preference for persons to sleep beneath one or more
bed sheets, covers, blankets, etc, coupled with the body's tendency to liberate heat during its normal operation translates to the well-known situation in which the person resting beneath the sheets cannot get comfortable because they are too hot, which is compounded by the proposition that if they remove the covers or sheets from themselves then they become too cold.
In
spite of these efforts, however, perfect control of the temperature of ambient surroundings of persons in a bed desiring to sleep has been fleeting, with particular difficulty for partners who share a bed with different sleep temperature preferences.
This ballooning effect can cause the blanket to swell to 24″ over the surface of the bedding, creating an undesirable condition.
This invention is also deficient in that it utilizes an air impervious material for the upper layer, which is an uncommon characteristic of normal bedding and shall cause substantial temperature and
humidity rise within the bed during moments when pressurized air is not supplied to the apparatus and thus causing discomfort to occupants who do not wish
continuous use of pressurized air during all sleeping times.
While each of the prior art devices and methods achieve to a greater or less extent their desired objectives, they are nevertheless not without features which have heretofore prevented their widespread adoption by large numbers of people.
The prior arts fails to teach a bedding apparatus that can evenly distribute a pressurized flow of air through a bed into both one or two independent zones, while not causing ballooning of bedding due to flow of air.
Moreover, the prior art introduces apparatus that introduce either foreign textures or objects to the user in the bed, which is a highly undesirable feature.
