The invention relates to a mattress for thermal comfort of animals in a livestock enclosure, wherein said comfort mattress (2) comprises at least one resilient layer (3) including: - at least one sealed chamber (4), intended to contain a first heat-transfer fluid, and - at least one watertight duct (5), intended to contain a second heat-transfer fluid, at least one section (51) of which passes through said at least one sealed chamber (4) between the upper (41) and lower (42) surfaces thereof so that said at least one section (51) is intended to soak / to bathe in said first heat-transfer fluid. Said at least one watertight duct (5) includes at least two through-orifices (55), to generate a circulation of said second heat-transfer fluid within said at least one watertight duct (5), between the through-orifices (55) thereof.本發明關於一種用於牲口圈地中的動物之熱舒適性的墊蓆,其中,此舒適墊蓆(2)包括至少一彈性層(3),其包括: -至少一密封室(4),用於容納第一熱轉移流體,以及 -至少一防水導管(5),用於容納第二熱轉移流體,其至少一區段(51)在至少一密封室的頂表面(41)及底表面(42)之間通過至少一密封室(4),使得至少一區段(51)用於浸泡/浸入到第一熱轉移流體中。 至少一防水導管(5)包括至少兩通孔(55),以在至少一防水導管(5)中於其通孔(55)之間產生第二熱轉移流體的循環。
