PURPOSE: A cushion mat is provided to maintain enough durability for long-term use and minimize the deformation of the cushion mat by heat. CONSTITUTION: A cushion mat(100) is comprised of an upper protection layer(110), a first foaming layer(120), a second foaming layer(130), and an air capture foaming layer(140). The first foaming layer is comprised of cross-linked polyethylene attached in the lower part of a protection layer. The second foaming layer is comprised of non cross-linked polyethylene attached in the lower part of the first foaming layer. The air capture foaming layer is attached in the lower part of the second foaming layer and comprised of a vent passage and a plurality of groove parts. The vent passage is arranged in order to communicate with the outside. A plurality of groove parts provides a space part which is able to capture inflow of external air to the inside through the vent passage. |
