This invention is about a mattress using thermoelectric module. In order to prevent lowering of the efficiency of thermoelectric module even when using the heating function, the mattress equipped with both heating and cooling functions, therefore usable regardless of season, characteristically consists of mattress part; temperature detection sensor to measure temperature of the mattress part; heating sink filled with heat transfer medium; circulation pipe located inside the mattress part that heats or cools the mattress part with flowing of the heat transfer medium; thermoelectric module located inside the heating sink that supplies the heat transfer medium to the circulation pipe after cooling or heating the heat transfer medium including action and reaction surfaces; normal to reverse conversion circuit to convert operation of the thermoelectric module; and means of heating attached to the reaction surface.
