Sleeping device comprising an active heat absorbing/releasing layer in combination with a spacer material layer

Abstract

The present invention relates to a sleeping device, such as a mattress, quilt or pillow, wherein the sleeping device is adapted to be used by a person during rest and comprises a core element, wherein said core element is covered by a first layer of a material 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, very good properties of minimizing temperature variations are obtained.

What is claimed is: 
     
         1 . A mattress comprising:
 a support element, wherein said support element is covered by a first layer of a material having temperature regulating properties by absorbing and releasing heat and a second layer of spacer material;   said spacer material comprised of a distance mesh positioned directly beneath said first layer, wherein said spacer material allows air circulation from the surroundings directly beneath said first layer; and   where the temperature regulating material comprises a phase change material.   
     
     
         2 . The mattress according to  claim 1 , wherein the mattress further comprises a third layer of down. 
     
     
         3 . The mattress according to  claim 2 , wherein the mattress further comprises a fourth layer of spacer material, said fourth layer positioned on the opposite site of the support element than the second layer, whereby each spacer material covers each side of said support element. 
     
     
         4 . A mattress according to  claim 2 , wherein the third layer of down comprises goose downs. 
     
     
         5 . A mattress as in one of  claim 1 , wherein the second layer has a thickness between 3 and 50 mm. 
     
     
         6 . A mattress as in one of  claim 2 , wherein the third layer has a thickness between 1 mm and 20 mm. 
     
     
         7 . A mattress as in one of  claim 1 , wherein the mattress further comprises at least one cover layer.
