    • PURPOSE:To generate lines of magnetic force affecting to deep portion by providing an elastic body made of cross linking foam polyethylene and the like on the upper face, a damper felt arranged with permanent magnets on the upper face is fixed on it, and covering a fiber layer holding the projections of the permanent magnets and the elastic body and a thin layer body on them. CONSTITUTION:A damper felt 4 made of blended felt and the like is stuck on an elastic body 1 with an adhesive, and several lines of continuously magnetizing magnets extended in the longitudinal direction of a mattress are fixed via an adhesive and the like. Lines of magnetic force are generated toward crests of S-poles from crests of ridges magnetized into N-poles, ridges are separated by valleys, the magnetic path length is extended, and the lines of magnetic force are generated in the perpendicular direction. The magnetic flux density at the position apart from both magnetic poles is increased. A fiber layer 7 made of chemical fibers is fixed on the damper felt 4. A thin layer body 10 made of a nonwoven fabric is covered on the fiber layer 7.
