Three-dimensional mesh structure

Abstract

The present invention provides a three-dimensional mesh structure that supports the body when the end area bears a local load, and does not cause a sense of disharmony due to the difference in hardness between the end area and the central area when the user unconsciously moves to the end area due to turning over while sleeping, etc., and does not bear a local load. The present invention is a three-dimensional mesh structure 1, wherein the apparent density of the end region 20 is more than 30% higher than the apparent density of the central region 10. The end region 20 has: an inner layer 21 located inside the thickness direction z of the three-dimensional mesh structure 1; and a surface layer 22 located on both sides of the inner layer 21 in the thickness direction z. The difference between the apparent density of the inner layer 21 and the apparent density of the central region 10 is less than 20%, the difference between the 25% compressive hardness in the end region 20 and the 25% compressive hardness in the central region 10 is less than 10%, and the 50% compressive hardness in the end region 20 is more than 15% higher than the 50% compressive hardness in the central region 10.
