The temperature control mattress comprises a surface layer and a structural layer which are attached to each other; a plurality of ventilation pipe sets capable of independently supplying air are arranged between the structural layer and the surface layer; each ventilation pipe set is provided with a plurality of air outlets, and a plurality of ventilation holes are formed in the surface layer; the ventilation holes can convey air exhausted by the air outlets to the side, away from the structural layer, of the surface layer so that multiple air supply areas can be formed in the surface layer; the ventilation pipe sets communicate with the air supply assemblies; and the air supply assemblies can output air sources of different temperatures so that temperature adjustment of the set air supply areas in the surface layer can be achieved. The temperature adjusting speed of the mattress can be increased, and the influence of the water heating mattress on a long-term bedridden patient is reduced.
