Elastic layer for a mattress structure designed for the comfort of animals in a breeding enclosure

An elastic layer for a mattress structure configured for comfort of animals in a livestock enclosure, said mattress structure being configured to cover the ground of an accommodation area bordered by a circulation corridor, said elastic layer comprising:

• two opposite faces including
• an upper face that is configured to undergo an elastic deformation and that includes at least one location configured for an animal to rest on, and
• a lower face,
• said upper and lower faces defining the thickness of said elastic layer,
• wherein said elastic layer is delimited by a plurality of borders including a rear longitudinal border configured to be located along the circulation corridor, a front longitudinal border configured to be located remote from the circulation corridor, and two lateral borders, at least the rear longitudinal border being formed by at least one one-piece fastening strip configured to receive a securing system configured to secure to the ground of said accommodation area, said at least one fastening strip being formed by at least one lip including
• a lower face,
• an upper face
• a free peripheral edge, and
• at least one reinforcement sub-layer,
• said upper and lower faces defining the thickness of said at least one lip,
• the thickness of said at least one lip being less than the thickness of said elastic layer,
• the at least one lip comprising one of:
• (i) a single lip, the upper face of the single lip extending in a continuation of the upper face of the elastic layer, and (ii) two superposed lips including an upper lip and a lower lip, the lower face of the upper lip and the upper face of the lower lip being opposite one another and independent from each other, the upper and lower lips delimiting a slot, extending in a part of the thickness of elastic layer, between the two opposite faces of the elastic layer.
