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.

Claims

exact text as granted — not AI-modified
