Sleeping devices comprising a combination of down filling and a temperature regulating material

Abstract

The present invention relates to a sleeping device, such as a pillow, mattress or quilt, wherein the sleeping device is adapted to be used by a person during rest and comprises a first layer of a material having temperature regulating properties and a second layer of down filling. By using a material with temperature regulating properties together with a layer of down filling, very good properties of minimizing temperature variations are obtained.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a sleeping device, such as a pillow, mattress or quilt. BACKGROUND OF THE INVENTION [0002] During sleep the human body goes through different phases, and in these phases the body temperature varies both as a result of internal temperature changes in the body during sleep and because of variations of the temperature in the surroundings. These temperature variations disturb the sleep. It is especially important for the sleep that the most important phase—the REM phase—is undisturbed, because in this phase the brain is recharged and prepared for the next waken period. Another effect of the temperature changes is that the quilt covering the person is kicked of during sleep, which often results in the person waking up later on freezing. Further, the temperature changes might also result in sweaty, wet sleeping devices. In both cases the temperature change does not only disturb the sleep, but might also result in sickness. OBJ...

AI Technical Summary

Benefits of technology

[0005] By using a material with temperature regulating properties together with a layer of down filling, very good properties of minimizing temperature variations are obtained. Compared to e.g. fiber filling, down filling has very good moist absorbing properties, and by minimizing the moist tests have shown that the functionality of temperature regulating materials such as e.g. phase change materials is improved considerably. Thereby the temperature regulating material can be used to fulfill the quite strict requirement to temperature variation which is necessary to get an undisturbed sleep—and especially an undisturbed REM sleep. Further, by using the temperature regulating material in the sleeping device it is avoided that the user gets sick, both because a better sleep improves the immune system and because the risk of the person unintentionally kicking of the quilt or making the sleeping devices wet because of sweat is reduced. Further, since the risk of the sleeping device getting sweaty is reduced, the frequency of which the sleeping devices and / or sleeping device covers have to be cleaned can be reduced.

[0013] In an embodiment the sleeping device is a mattress. Thereby temperature variation around the body of the user can be minimized.

Problems solved by technology

These temperature variations disturb the sleep.

Another effect of the temperature changes is that the quilt covering the person is kicked of during sleep, which often results in the person waking up later on freezing.

Further, the temperature changes might also result in sweaty, wet sleeping devices.

In both cases the temperature change does not only disturb the sleep, but might also result in sickness.
