Mattress Comprising An Active Heat Absorbing/Releasing Layer In Combination With A Down Layer

Abstract

The present invention relates to a mattress (101), wherein the mattress is adapted to be used by a person during rest and comprises a support element (105), wherein said support element is covered by a first layer of a material (107) having temperature regulating properties by absorbing and releasing heat and a second layer of down. By using a material with temperature regulating properties together with a layer of down filling (109), very good properties of minimizing temperature variations are obtained.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a mattress. 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 off during sleep, which often results in the person waking up later on freezing. Further, the temperature changes might also result in a sweaty, wet mattress. In both cases the temperature change does not only disturb the sleep, but might also result in sickness.

AI Technical Summary

Benefits of technology

"The patent describes a mattress that solves problems related to temperature variations during sleep. The mattress has a support element covered by two layers: a first layer made of a material with temperature regulating properties and a second layer made of down. The use of a temperature regulating material and down filling has shown good results in minimizing temperature variations. The mattress also reduces the risk of getting sick, improves the immune system, and reduces the need for cleaning. The temperature regulating material can be a phase change material, and the mattress may also have a third layer of spacer material to improve the temperature regulating properties and minimize moist. The second layer of down can be made of goose downs, which are good at absorbing moist. The mattress can also have a cover layer for protection."

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 off during sleep, which often results in the person waking up later on freezing.

Further, the temperature changes might also result in a sweaty, wet mattress.

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

A problem with this solution is that during sleep moist from the body is generated and the moist is then absorbed in the layer following the phase change material, which typically either is the core of the mattress or a layer of synthetic filling between the core and the phase change material.

The moist decreases the effect of the phase change material considerably, whereby the introduction of the phase change material does not sufficiently solve the problem of minimising the temperature variations during sleep.

None of the above documents solves the problem with moist described above.
