The invention discloses a multifunctional magnetic health-care shim belonging to the technical field of 
health protection supplies. The shim comprises 8 
layers, sequentially including a three-proofing and two-resistance surface cloth layer, an anti-acarien cloth layer, a 
far infrared bamboo 
fiber needle-punched cotton layer, a 
magnet layer capable of generating a stereo biological 
magnetic field, an interwoven cloth layer, a matlin cashmere needle-punched cotton layer, a high-energy 
silver ion shielding cloth layer and a three-proofing two-resistance bottom cloth layer from top to bottom. The multifunctional magnetic health-care shim disclosed by the embodiment of the invention integrates multiple functions, namely, one the one hand, the 
blood circulation and the micro-circulation of a 
human body can be improved continuously under the common action of the biological 
magnetic field, 
far infrared and negative 
oxygen ion to enhance the health-care effects of the 
immunity, the self-healing ability and the resistance of the 
human body, on the other hand, the functions of 
waterproofing, oilproofing, 
static electricity prevention, bacterium and acarien prevention, dampness prevention, heat preservation and air refreshing can be achieved, also the functions of effectively shielding harmful electronic 
radiation, and achieving safety, 
sanitation and environment friendliness effects are achieved, and besides, the shim is manufactured perfectly, light in weight, portable, wide in application range and matched with any conventional mattress.
