摘要

The mattress (1) has upper layer (2) and lower layer (4) with support surfaces (3,5), and a heating element (6) which is eccentrically provided between upper layer and lower layer. The distance (A) between the heating element and the support surface (5) is smaller than the distance (B) between the heating element and the support surface. An air-permeable intermediate layer (7) is provided between the heating element and the upper layer.
